| Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | 1. Nature of the Business and Operations and LiquidityNature of the Business and Operations American Superconductor Corporation (together with its subsidiaries, “AMSC®”or the “Company”) was founded on April 9, 1987. The Company is a leading system provider of megawatt-scale power solutions that enhance the performance of the power grid, protect the Navy’s fleet, and lower the cost of wind power. The Company’s system level products leverage its proprietary “smart materials” and “smart software and controls” to provide enhanced resiliency and improved performance of megawatt-scale power flow.These unaudited condensed consolidated financial statements of the Company have been prepared on a going concern basis in accordance with United States generally accepted accounting principles (“GAAP”) and the Securities and Exchange Commission’s (“SEC”) instructions to Form 10 -Q. The going concern basis of presentation assumes that the Company will continue operations and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to those instructions. The year-end condensed balance sheet data was derived from audited financial statements but does not include all disclosures required by GAAP. The unaudited condensed consolidated financial statements, in the opinion of management, reflect all adjustments (consisting of normal recurring adjustments) necessary for a fair statement of the results for the interim periods ended June 30, 2019 2018 June 30, 2019 not necessarily indicative of results which may be expected for the full year. The interim condensed consolidated financial statements, and notes thereto, should be read in conjunction with the audited consolidated financial statements for the year ended March 31, 2019 10 -K for the year ended March 31, 2019 June 5, 2019. Liquidity The Company has historically experienced recurring operating losses and as of June 30, 2019 965.1 June 30, 2019 74.0 no outstanding debt other than ordinary trade payables. Cash used in operations for the three June 30, 2019 5.9 On July 3, 2018, the Company and its wholly-owned subsidiaries Suzhou AMSC Superconductor Co. Ltd. (“AMSC China”) and AMSC Austria GMBH (“AMSC Austria”) entered into a settlement agreement (the “Settlement Agreement”) with Sinovel Wind Group Co., Ltd. (“Sinovel”). The Settlement Agreement settles the litigation and arbitration proceedings between the Company and Sinovel. Under the terms of the Settlement Agreement, Sinovel agreed to pay AMSC China an aggregate cash amount in Renminbi (“RMB”) equivalent to $57.5 million, consisting of two installments. Sinovel paid the first installment of the RMB equivalent of $32.5 million on July 4, 2018, which was repatriated to the Company during the nine months ended December 31, 2018, and paid the second installment of the RMB equivalent of $25.0 million on December 27, 2018. The Company’s fiscal 2018 results included the net gain received from the settlement with Sinovel of $52.7 million.On February 1, 2018, ASC Devens LLC (the “Seller”), a wholly-owned subsidiary of the Company, entered into a Purchase and Sale Agreement (the “PSA”) with 64 Jackson, LLC (the “Purchaser”) and Stewart Title Guaranty Company (“Escrow Agent”), to effectuate the sale of certain real property located at 64 Jackson Road, Devens, Massachusetts, including the building that had served as the Company’s headquarters (collectively, the “Property”), in exchange for total consideration of $23.0 million, composed of (i) cash consideration of $17.0 million, and (ii) a $6.0 million subordinated secured commercial promissory note payable to the Company (the “Seller Note”). Subsequently, the Seller, the Purchaser and Jackson 64 MGI, LLC (“Assignee”) entered into an Assignment of Purchase and Sale Agreement (the “Assignment Agreement”), pursuant to which the Purchaser assigned all of its rights and interests in the PSA to the Assignee and the Assignee agreed to assume all of the Purchaser’s obligations and liabilities under the PSA. The transaction closed on March 28, 2018, at which time the Company received, from the Assignee, cash consideration, net of certain agreed upon closing costs, of $16.9 million, and the Seller Note at an interest rate of 1.96%. The Seller Note was secured by a subordinated second mortgage on the Property and a subordinated second assignment of leases and rents. The Company received the first $3.0 million payment due pursuant to the Seller Note on March 28, 2019 and the second $3.0 million payment plus interest on May 23, 2019. In December 2015, the Company entered into a set of strategic agreements valued at approximately $210.0 million with Inox Wind Ltd. (“Inox” or “Inox Wind”), which includes a multi-year supply contract pursuant to which the Company will supply electrical control systems to Inox and a license agreement allowing Inox to manufacture a limited number of electrical control systems. After Inox purchases the specified number of electrical control systems required under the terms of the supply contract, Inox agreed that the Company will continue as Inox’s preferred supplier and Inox will be required to purchase from the Company a majority of its electrical control systems requirements for an additional three -year period.The Company believes that based on the information presented above and its quarterly management assessment, it has sufficient liquidity to fund its operations and capital expenditures for the next twelve months following the issuance of the financial statements for the three June 30, 2019 no assurance that the Company will be able to continue to raise additional capital, on favorable terms or at all, from other sources or execute on any other means of improving liquidity described above. |

| Revenue from Contract with Customer [Text Block] | 2. Revenue RecognitionOn April 1, 2018, the Company adopted Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers, and all the related amendments and applied it to all contracts that were not completed as of April 1, 2018 using the modified retrospective method. The Company’s revenues in its Grid segment are derived primarily through enabling the transmission and distribution of power, providing planning services that allow it to identify power grid needs and risks, and developing ship protection systems for the U.S. Navy. The Company’s revenues in its Wind segment are derived primarily through supplying advanced power electronics and control systems, licensing its highly engineered wind turbine designs, and providing extensive customer support services to wind turbine manufacturers. The Company records revenue based on a five -step model in accordance with ASC 606. For its customer contracts, the Company identifies the performance obligations, determines the transaction price, allocates the contract transaction price to the performance obligations, and recognizes the revenue when (or as) control of goods or services is transferred to the customer. As of June 30, 2019 78 In the Company's equipment and system product line, each contract with a customer summarizes each product sold to a customer, which typically represent distinct performance obligations. A contract's transaction price is allocated to each distinct performance obligation using the respective standalone selling price which is determined primarily using the cost plus expected margin approach and recognized as revenue when, or as, the performance obligation is satisfied. The majority of the Company’s product sales transfer control to the customer in line with the contracted delivery terms and revenue is recorded at the point in time when title and risk transfer to the customer, as the Company has determined that this is the point in time that control transfers to the customer. The Company's equipment and system product line includes contracts which do not meet the requirements of an exchange transaction and therefore do not fall within the scope of ASC 606. As these non-exchange transaction contracts are considered grant revenue and do not fall within any specific accounting literature, the Company follows guidance within ASC 606 by analogy to recognize grant revenue over time. In the three months ended June 30, 2019 the Company recorded $0.4 million in grant revenue, which is included in the Company’s Grid Revenue. There was no grant revenue in the prior year.In the Company's service and technology development product line, there are several different types of transactions and each begins with a contract with a customer that summarizes each product sold to a customer, which typically represents distinct performance obligations. The technology development transactions are primarily for activities that have no alternative use and for which a profit can be expected throughout the life of the contract. In these cases, the revenue is recognized over time, but in the instances where the profit cannot be assured throughout the entire contract then the revenue is recognized at a point in time. Each contract's transaction price is allocated to each distinct performance obligation using the respective standalone selling price which is determined primarily using the cost plus expected margin approach. The ongoing service transactions are for service contracts that provide benefit to the customer simultaneously as the Company performs its obligations, and therefore this revenue is recognized ratably over time throughout the effective period of these contracts. The transaction prices on these contracts are allocated based on an adjusted market approach which is re-assessed annually for reasonableness. The field service transactions include contracts for delivery of goods and completion of services made at the customer's requests, which are not deemed satisfied until the work has been completed and/or the requested goods have been delivered, so all of this revenue is recognized at the point in time when the control changes, and at allocated prices based on the adjusted market approach driven by standard price lists. The royalty transactions are related to certain contract terms on transactions in the Company's equipment and systems product line based on activity as specified in the contracts. The transaction prices of these agreements are calculated based on an adjusted market approach as specified in the contract. The Company reports royalty revenue for usage-based royalties when the sales have occurred. In circumstances when collectability is not assured and a contract does not exist under ASC 606, revenue is deferred until a non-refundable payment has been received for substantially all the amount that is due and there are no further remaining performance obligations.The Company's service contracts can include a purchase order from a customer for specific goods in which each item is a distinct performance obligation satisfied at a point in time at which control of the goods is transferred to the customer which occurs based on the contracted delivery terms or when the requested service work has been completed. The transaction price for these goods is allocated based on the adjusted market approach considering similar transactions under similar circumstances. Service contracts are also derived from ongoing maintenance contracts and extended service-type warranty contracts. In these transactions, the Company is contracted to provide an ongoing service over a specified period of time. As the customer is consuming the benefits as the service is being provided the revenue is recognized over time ratably. The Company’s policy is to not accept volume discounts, product returns, or rebates and allowances within its contracts. In the event a contract was approved with any of these terms, it would be evaluated for variable consideration, estimated and recorded as a reduction of revenue in the same period the related product revenue was recorded.The Company provides assurance-type warranties on all product sales for a term of typically one to two years, and extended service-type warranties at the customers’ option for an additional term ranging up to four additional years. The Company accrues for the estimated warranty costs for assurance warranties at the time of sale based on historical warranty experience plus any known or expected changes in warranty exposure. For all extended service-type warranties, the Company recognizes the revenue ratably over time during the effective period of the services.The Company records revenue net of sales tax, value added tax, excise tax and other taxes collected concurrent with revenue-producing activities. The Company has elected to recognize the cost for freight and shipping when control over the products sold passes to customers and revenue is recognized. The Company has elected to recognize incremental costs of obtaining a contract as expense when incurred except in contracts where the amortization period would exceed twelve months; in such cases the long term amount will be assessed for materiality. The Company has elected to not adjust the promised amount of consideration for the effects of a significant financing component if the period of financing is twelve months or less.The Company’s contracts with customers do not typically include extended payment terms and may include milestone billing over the life of the contract. Payment terms vary by contract type and type of customer and generally range from 30 to 60 days from delivery.The following tables disaggregate the Company’s revenue by product line and by shipment destination:
As of June 30, 2019 June 30, 2018 7, “Accounts Receivable” and Note 8, “Inventory” for a reconciliation to the condensed consolidated balance sheets) and contract liabilities, which are included in the current portion and long term portion of “deferred revenue” in the Company’s condensed consolidated balance sheets, are as follows:
The Company’s remaining performance obligations represent the unrecognized revenue value of the Company’s contractual commitments. The Company’s performance obligations may vary significantly each reporting period based on the timing of major new contractual commitments. As of June 30, 2019 606 to be recognized in the next twelve months of approximately $54.7 9.8 thirteen to sixty months. The remaining performance obligations are subject to customer actions and therefore the timing of revenue recognition cannot be reasonably estimated. The twelve month performance obligations include anticipated shipments to Inox based on the twelve month rolling forecast provided by Inox on the multi-year supply contract. The quantities specified in any forecast provided by Inox related to the multi-year supply contract are firm and irrevocable for the first three months of a twelve month rolling forecast. The timing of the performance obligations beyond the twelve month forecast provided by Inox are not determinable and therefore are not included in the total remaining performance obligations.The following table sets forth customers who represented 10% or more of the Company’s total revenues for the three June 30, 2019 2018

| Earnings Per Share [Text Block] | 4. Computation of Net Loss per Common ShareBasic net loss per share (“EPS”) is computed by dividing net loss by the weighted-average number of common shares outstanding for the period. Where applicable, diluted EPS is computed by dividing the net loss by the weighted-average number of common shares and dilutive common equivalent shares outstanding during the period, calculated using the treasury stock method. Common equivalent shares include the effect of restricted stock, exercise of stock options and warrants and contingently issuable shares. Stock options and warrants that are out-of-the-money with exercise prices greater than the average market price of the underlying Common Shares and shares of performance based restricted stock where the contingency was not met are excluded from the computation of diluted EPS as the effect of their inclusion would be anti-dilutive. For the three June 30, 2019 1.0 not included in the calculation of diluted EPS as they were considered anti-dilutive, of which 0.2 0.8 three June 30, 2018 1.1 million shares were not included in the calculation of diluted EPS as they were considered anti-dilutive, of which 0.2 million shares relate to outstanding stock options, and 0.9 million shares relate to outstanding warrants.The following table reconciles the numerators and denominators of the earnings per share calculation for the three June 30, 2019 2018

| Fair Value Disclosures [Text Block] | 6. Fair Value MeasurementsA valuation hierarchy for disclosure of the inputs to valuation used to measure fair value has been established. This hierarchy prioritizes the inputs into three broad levels as follows:
The Company provides a gross presentation of activity within Level 3 measurement roll-forward and details of transfers in and out of Level 1 and 2 measurements. A change in the hierarchy of an investment from its current level is reflected in the period during which the pricing methodology of such investment changes. Disclosure of the transfer of securities from Level 1 to Level 2 or Level 3 is made in the event that the related security is significant to total cash and investments. The Company did not have any transfers of assets and liabilities from Level 1, Level 2 or Level 3 of the fair value measurement hierarchy during the three June 30, 2019 A financial asset’s or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The following table provides the assets and liabilities carried at fair value on a recurring basis, measured as of June 30, 2019 March 31, 2019
The table below reflects the activity for the Company’s major classes of liabilities measured at fair value on a recurring basis (in thousands):
Valuation Techniques Cash Equivalents Cash equivalents consist of highly liquid instruments with maturities of three months or less that are regarded as high quality, low risk investments and are measured using such inputs as quoted prices, and are classified within Level 1 of the valuation hierarchy. Cash equivalents consist principally of certificates of deposits and money market accounts.Warrants Warrants were issued in conjunction with an equity offering to Hudson Bay Capital in November 2014 and a Loan and Security Agreement with Hercules Technology Growth Capital, Inc. (“Hercules”). The warrants issued to Hercules were exercised on April 8, 2019. Outstanding warrants are subject to revaluation at each balance sheet date, and any change in fair value will be recorded as a change in fair value in derivatives and warrants until the earlier of their exercise or expiration.The Company relies on various assumptions in a lattice model to determine the fair value of warrants. The Company has valued the warrants within Level 3 of the valuation hierarchy. See Note 13, “Warrants and Derivative Liabilities,” for additional information including a discussion of the warrants and the valuation assumptions used. |

| Notes Receivable [Text Block] | 9. Note ReceivableThe Company entered into the PSA dated February 1, 2018, for the sale of the Devens facility (including land, building and building improvements) located at 64 Jackson Road, Devens, Massachusetts to 64 Jackson, LLC, a limited liability company (subsequently assigned to Jackson 64 MGI, LLC) in the amount of $23.0 million. The terms for payment included a $1.0 million security deposit, and a note receivable for $6.0 million payable to the Company with the remaining cash net of certain adjustments for closing costs at the date of settlement. The note receivable was due in two $3.0 million installments plus accrued interest at a rate of 1.96% on March 31, 2019 and March 31, 2020. The note was subordinate to East Boston Savings Bank's mortgage on the Devens property. The first installment was paid on March 28, 2019 and the second installment was paid on May 23, 2019. The note receivable was discounted to its present value of $5.7 million utilizing a discount rate of 6%, which was based on management’s assessment of what an appropriate loan at current market rates would be. The $0.3 million discount was recorded as an offset to the long term portion of the note receivable. In addition, the resulting gain of $0.1 million from the sale of the Devens property which was deferred previously was recorded as a component of the cumulative effect of an accounting change upon the adoption of Accounting Standards Update ("ASU") 2017 -05 Other Income - Gains and Losses from the Derecognition of Non-financial Assets (Subtopic which was issued as a part of ASU 610 -20 ) 2014 -09 Revenue from Contracts with Customers (Topic .

| Income Tax Disclosure [Text Block] | 12. Income TaxesThe Company recorded an income tax expense of $ 0.2 $0.1 million in the three June 30, 2019 2018 Accounting for income taxes requires a two -step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if, based on the technical merits, it is more likely than not the position will be sustained upon audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. The Company re-evaluates these uncertain tax positions on a quarterly basis. The evaluation is based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit and new audit activity. Any changes in these factors could result in the recognition of a tax benefit or an additional charge to the tax provision. The Company did not identify any uncertain tax positions in the three June 30, 2019 not have any gross unrecognized tax benefits as of March 31, 2019 |

| Derivative Instruments and Hedging Activities Disclosure [Text Block] | 13. Warrants and Derivative LiabilitiesThe Company accounts for its warrants and contingent consideration as liabilities due to certain adjustment provisions within the instruments, which require that they be recorded at fair value. The warrants are subject to revaluation at each balance sheet date and any change in fair value is recorded as a change in fair value of warrants until the earlier of its expiration or its exercise at which time the warrant liability will be reclassified to equity. The Company calculated the fair value of the warrants utilizing an integrated lattice model. See Note 6, "Fair Value Measurements", for further discussion.Hercules Warrants On December 19, 2014, the Company entered into a second amendment to the Loan and Security Agreement with Hercules (the "Hercules Second Amendment"). In conjunction with the Hercules Second Amendment, the Company issued Hercules a warrant to purchase 58,823 shares of the Company’s common stock (the "Hercules Warrant") which replaced the First Warrant and the Second Warrant. The Hercules Warrant was exercisable at any time after its issuance at an exercise price of $7.85 per share, subject to certain price-based and other anti-dilution adjustments, including the equity offering in May 2017, the acquisition of ITC with common stock in September 2017 and sales of common stock under the ATM entered into in January 2017. This warrant had a fair value of $0.4 million as of March 31, 2019. On April 8, 2019 Hercules notified the Company of its intent to exercise this warrant on a cashless basis. Hercules received 22,821 shares of the Company's common stock on April 17, 2019. As a result of this exercise the Company recorded a net gain of $0.1 million to change in fair value of warrants, resulting from the decrease in the fair value upon exercise of the Hercules Warrant during the three months ended June 30, 2019. November 2014 WarrantOn November 13, 2014, the Company completed an offering of 909,090 units of the Company’s common stock with Hudson Bay Capital. Each unit consisted of one share of the Company’s common stock and 0.9 of a warrant to purchase one share of common stock, or a warrant to purchase in the aggregate 818,181 shares (the “November 2014 Warrant”). The November 2014 Warrant is exercisable at any time, at an exercise price equal to $7.81 per share, subject to certain price-based and other anti-dilution adjustments including those noted above, and expires on November 13, 2019. Following is a summary of the key assumptions used to calculate the fair value of the November 2014 Warrant:
The Company recorded a net gain of $ 2.9 decrease in the fair value of the November 2014 Warrant during the three June 30, 2019 $0.5 million resulting from the increase in the fair value of the November 2014 Warrant during the three June 30, 2018 |

| Lessee, Operating Leases [Text Block] | 14. Leases On April 1, 2019, the Company adopted ASU 2016 -02, Leases (Topic ("ASC 842 )842" ), using the modified retrospective approach. The Company elected the package of practical expedients available in the standard and as a result, did not reassess the lease classification of existing contracts or leases or the initial direct costs associated with existing leases. The Company did not elect the hindsight practical expedient, and evaluated lease terms for existing leases. The Company has also elected the practical expedient to not separate lease components and non-lease components and will account for the leases as a single lease component for all classes of leases.As a result of the adoption of ASC 842, the Company recognized lease right-of-use assets of $3.8 million, and operating lease liabilities of $3.8 million. There was no impact to the condensed consolidated statements of operations or stockholders' equity for the adoption of ASC 842. No impairment was recognized on the right-of-use asset upon adoption. These adjustments are detailed as follows:
All significant lease arrangements are recognized at lease commencement. Operating lease right–of-use assets and lease liabilities are recognized at commencement. The operating lease right-of-use asset includes any lease payments related to initial direct cost and prepayments and excludes any lease incentives. Lease expense is recognized on a straight-line basis over the lease term. The Company enters into a variety of operating lease agreements through the normal course of its business, but primarily real estate leases to support its operations. The agreements generally provide for fixed minimum rental payments and the payment of real estate taxes and insurance. Many of these leases have one or more renewal options that allow the Company, at its discretion, to renew the lease for varying periods up to five years or to terminate the lease. Only renewal options or termination rights that the Company believed were likely to be exercised were included in the lease calculations.The Company also enters into leases for vehicles, IT equipment and service agreements, and other leases related to its manufacturing operations that are also included in the right-of-use asset and lease liability accounts if they are for a term of longer than twelve months. However, many of these leases are either short-term in nature or immaterial. The Company has made the policy election to exclude short term leases from the balance sheet. The discount rate was calculated using an incremental borrowing rate based on an assessment prepared by the Company through the use of Company credit ratings, consideration of its lease populations potential risk to its total capital structure, and a market rate for a collateralized loan for its risk profile, calculated by a third party. The Company elected to apply the discount rate using the remaining lease term at the date of adoption.The Company did not identify any leases that are classified as financing leases.Supplemental balance sheet information related to leases at June 30, 2019 are as follows:
The costs related to the Company's leases for the three months ended June 30, 2019 are as follows:
The Company’s estimated minimum future lease obligations under the Company's leases are as follows:

Commitments and ContingenciesLegal Contingencies From time to time, the Company is involved in legal and administrative proceedings and claims of various types. The Company records a liability in its consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. The Company reviews these estimates each accounting period as additional information is known and adjusts the loss provision when appropriate. If a matter is both probable to result in a liability and the amounts of loss can be reasonably estimated, the Company estimates and discloses the possible loss or range of loss to the extent necessary to make the consolidated financial statements not misleading. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in its consolidated financial statements.Other The Company enters into long-term construction contracts with customers that require the Company to obtain performance bonds.

| Segment Reporting Disclosure [Text Block] | 17. Business SegmentsThe Company reports its financial results in two reportable business segments: Grid and Wind.Through the Company’s power grid offerings, the Grid business segment enables electric utilities, industrial facilities, and renewable energy project developers to connect, transmit and distribute power through our transmission planning services, power electronics, and superconductor-based systems. The sales process is enabled by transmission planning services that allow it to identify power grid congestion, poor power quality and other risks, which helps the Company determine how its solutions can improve network performance. These services often lead to sales of grid interconnection solutions for wind farms and solar power plants, power quality systems, and transmission and distribution cable systems. The Company also sells ship protection products to the U.S. Navy through its Grid business segment. Through the Company’s wind power offerings, the Wind business segment enables manufacturers to field highly competitive wind turbines through our advanced power electronics and control system products, engineered designs, and support services. The Company supplies advanced power electronics and control systems, licenses its highly engineered wind turbine designs, and provides extensive customer support services to wind turbine manufacturers. The Company’s design portfolio includes a broad range of drive trains and power ratings of 2 megawatts ("MWs") and higher. The Company provides a broad range of power electronics and software-based control systems that are highly integrated and designed for optimized performance, efficiency, and grid compatibility.The operating results for the two business segments are as follows (in thousands):
The accounting policies of the business segments are the same as those for the consolidated Company. The Company’s business segments have been determined in accordance with the Company’s internal management structure, which is organized based on operating activities. The Company evaluates performance based upon several factors, of which the primary financial measures are segment revenues and segment operating loss. The disaggregated financial results of the segments reflect allocation of certain functional expense categories consistent with the basis and manner in which Company management internally disaggregates financial information for the purpose of assisting in making internal operating decisions. In addition, certain corporate expenses which the Company does not believe are specifically attributable or allocable to either of the two business segments have been excluded from the segment operating loss.Unallocated corporate expenses primarily consist of stock-based compensation expense of $ 0.2 $0.8 million in the three June 30, 2019 2018 $0.3 million in the three June 30, 2018 Total assets for the two business segments as of June 30, 2019 March 31, 2019

| New Accounting Pronouncements and Changes in Accounting Principles [Text Block] | 18. Recent Accounting PronouncementsIn February 2016, the FASB issued ASU 2016 -02, Leases (Topic . The guidance in this ASU supersedes the leasing guidance in Topic 842 )840, Leases . Under the new guidance, lessees are required to recognize lease assets and lease liabilities on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. This ASU and its amendments are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years.
ASU 2016 -02 became effective on April 1, 2019, and the Company adopted the standard using the modified retrospective transition method, which impacted all leases existing at, or entered into after, the period of adoption. For all leases existing at the time of adoption the Company recognized a right-of-use asset and lease liability on the balance sheet. See Note 14 "Leases" for additional information.In June 2016, the FASB issued ASU 2016 -13, Financial Instruments-Credit Losses (Topic . The amendments in ASU 326 ): Measurement of Credit Losses on Financial Instruments2016 -13 will provide more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The ASU is effective for annual reporting periods beginning after December 15, 2019, including interim periods within that year. The Company is currently evaluating the impact, if any, the adoption of ASU 2016 -13 may have on its consolidated financial statements.In July 2017, the FASB issued ASU 2017 -11, Earnings per Share (Topic 260 ), Distinguishing Liabilities from Equity (Topic . The amendments in ASU 480 ), and Derivatives and Hedging (Topic 815 )2017 -11 provide guidance for freestanding equity-linked financial instruments, such as warrants and conversion options in convertible debt or preferred stock, and should no longer be accounted for as a derivative liability at fair value as a result of the existence of a down round feature. The ASU is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those periods. As of April 1, 2019, the Company has adopted ASU 2017 -11 and noted no significant impact on its consolidated financial statements, primarily due to the put option feature within the Company's warrant agreements which requires continued liability classification under ASC 480. In August 2017, the FASB issued ASU 2017 -12, Derivatives and Hedging (Topic . The amendments in ASU 815 ): Targeted Improvements to Accounting for Hedging Activities2017 -12 provide improved financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. In addition, the amendments in this update make certain targeted improvements to simplify the application of the hedge accounting guidance. The ASU is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those periods. As of April 1, 2019, the Company has adopted ASU 2017 -12 and noted no significant impact on its consolidated financial statements, primarily due to the fact that there are no longer any hedging instruments included in its results.In June 2018, the FASB issued ASU 2018 -08, Not -For-Profit Entities (Topic 958 ): Clarifying the Scope and the Accounting Guidance for Contributions Received and Contributions Made. The amendments in ASU 2018 -08 assist entities in (1 ) evaluating whether transactions should be accounted for as contributions (nonreciprocal transactions) within the scope of Topic 958, Not -for-Profit Entities, or as exchange (reciprocal) transactions subject to other guidance and (2 ) determining whether a contribution is conditional. The ASU is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those periods. As of April 1, 2019, the Company has adopted ASU 2018 -08 and noted additional disclosures within its revenue footnote to appropriately present the revenue related to its grant revenue.In August 2018, the FASB issued ASU 2018 -13, Fair Value Measurement (Topic . The amendments in ASU 820 ): Changes to the Disclosure Requirements for Fair Value Measurement2018 -13 provide for increased effectiveness of the disclosures made around fair value measurements while including consideration for costs and benefits. The ASU is effective for annual reporting periods beginning after December 15, 2019, including interim periods within those periods. The Company is currently evaluating the impact the adoption of ASU 2018 -13 may have on its consolidated financial statements. |

| Accounting Policies [Abstract] | |
| Nature of Business and Operations, Policy [Policy Text Block] | Nature of the Business and Operations American Superconductor Corporation (together with its subsidiaries, “AMSC®”or the “Company”) was founded on April 9, 1987. The Company is a leading system provider of megawatt-scale power solutions that enhance the performance of the power grid, protect the Navy’s fleet, and lower the cost of wind power. The Company’s system level products leverage its proprietary “smart materials” and “smart software and controls” to provide enhanced resiliency and improved performance of megawatt-scale power flow.These unaudited condensed consolidated financial statements of the Company have been prepared on a going concern basis in accordance with United States generally accepted accounting principles (“GAAP”) and the Securities and Exchange Commission’s (“SEC”) instructions to Form 10 -Q. The going concern basis of presentation assumes that the Company will continue operations and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to those instructions.
