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
