American Superconductor Corporation

American Superconductor Corporation (AMSC) designs, develops, and deploys power control solutions for traditional grids, renewable energy facilities, industrial applications, and naval/marine systems. The company uses proprietary smart materials, including high-temperature superconducting (HTS) wire, and software-driven controls to deliver integrated, system-level power electronics and protection solutions.

What the company does (by market segment)

  • Grid and transmission: Megawatt-scale power control systems for transmission, distribution, and urban grid infrastructure, including solutions for grids with distributed generation.
  • Wind: Wind turbine design, electrical control systems (ECS), and related services for turbine manufacturers and operators.
  • Naval/marine: Power protection and power management solutions for naval vessels, including HTS-based degaussing and ship protection systems (SPS) used by the U.S. and allied fleets.
  • Manufacturing and capabilities expansion through strategic acquisitions (Comtrafo in Brazil; Megatran/NWL in the U.S.).

Business segments

  • Grid (power grid and grid-support solutions)
    • D-VAR systems (dynamic voltage and reactive power control)
    • Transformers and DC rectifiers for industrial power conversion and grid use
    • Power supplies and military-grade magnetics
    • Power factor correction and harmonic filtering
    • actiVAR systems (fast-switching reactive compensation)
    • armorVAR systems (reactive compensation with integrated PF correction and harmonic filtering; can include D-VAR components)
    • D-VAR VVO (distribution-voltage optimization for networks with distributed generation)
    • REG systems (ring/loop configurations for urban/substation interconnection that use Amperium HTS wire)
    • HTS-based ship-protection solutions and other grid-enhancing technologies
    • Amperium HTS wire (high-temperature superconducting conductor) and associated systems
  • Wind
    • Electrical control systems (ECS) for wind turbines
    • Wind turbine designs (2 MW+ platforms; licensing revenue and ECS sales)
    • Customer support services (plant design, supply chain localization, training, installation, and maintenance)
    • Licensing of wind turbine designs and related know-how

Key products, capabilities, and technology

  • Amperium HTS wire for power cables, fault current limiters, and other grid applications
  • PowerModule™ power converters (integrated hardware and software) used in D-VAR and wind turbine systems
  • HTS-based ship protection systems (SPS) with reduced weight and energy consumption
  • D-VAR, REG, actiVAR, armorVAR, D-VAR VVO, power factor correction, and harmonic filtering solutions for grid reliability and power quality
  • Wind ECS and wind turbine designs with licensing and field services
  • Substation and urban-grid interconnection solutions to improve reliability and resilience

Customers and market presence

  • Global customer base with more than 100 grid-market customers since inception
  • Wind customers include licensing partners and ECS buyers; Inox Wind accounted for 15% of revenue in fiscal 2025 and Fuji Bridex accounted for 10% of revenue in fiscal 2025
  • Navy and defense customers, including the U.S. Navy, for ship protection and power systems
  • Local sales and field service presence in Australia, Canada, India, South Korea, the United Kingdom, and other markets
  • Offers turnkey system sales (design, deployment, and integration) in addition to component-level licensing and sales

Acquisitions and corporate actions

  • December 5, 2025: Completed acquisition of Comtrafo Indústria de Transformadores Elétricos S.A. (Brazil). Comtrafo operates within the Grid segment.
  • August 1, 2024: Acquired Megatran Industries, Inc. Megatran and its subsidiary NWL, Inc. are part of the Grid segment; NWL is a U.S.-based producer of engineered power conversion solutions.
