Ecosystem
Customers / end markets
- Midea
- Gree
- Hisense
- Haier
- EV OEMs and Tier 1s, industrial drive makers, renewable-energy inverter suppliers, charging equipment vendors, rail, welding, UPS, and power-supply customers
- Named customer claims should be shown only when source-specific; module qualification can be long and application-specific
Competitors
- Infineon
Global peer set
- Infineon, Mitsubishi Electric, Fuji Electric, Semikron Danfoss, ON Semiconductor, STMicroelectronics, and Wolfspeed depending on IGBT versus SiC category
- Domestic comparison set includes CRRC Times Electric, BYD Semiconductor, Silan Micro, and other Chinese power-device/module players
Competitive position
- StarPower is a power-module and device supplier, not a general semiconductor company.
- The strongest China story is in IGBT module substitution for EV and industrial applications; the harder frontier is SiC device/module performance and automotive qualification.
- Dashboard treatment should separate design/module capability from upstream substrate, epitaxy, and wafer-fab dependencies.
- Chinese power-module leader with commercial IGBT and SiC products in EV and industrial sockets; SiC on 800V platforms since 2022, narrowing the gap to global leaders.
- Dependence on upstream SiC and IGBT wafer/substrate supply; specific automotive OEM concentration unclear.
- Global comparables: Infineon, Mitsubishi Electric, Fuji Electric, Semikron Danfoss, ON Semiconductor, STMicroelectronics, and Wolfspeed depending on IGBT versus SiC category.
- Global comparables: Domestic comparison set includes CRRC Times Electric, BYD Semiconductor, Silan Micro, and other Chinese power-device/module players.
- IGBT module competitiveness depends on die performance, thermal management, packaging, reliability, and automotive qualification.

Answered questions
Last reviewed 2026-07-01How much revenue comes from EV traction versus industrial/renewable/other applications?
Against Infineon, Infineon, Mitsubishi Electric, Fuji Electric, Semikron Danfoss, ON Semiconductor, STMicroelectronics, and Wolfspeed depending on IGBT versus SiC category, and Domestic comparison set includes CRRC Times Electric, BYD Semiconductor, Silan Micro, and other Chinese power-device/module players: Chinese power-module leader with commercial IGBT and SiC products in EV and industrial sockets; SiC on 800V platforms since 2022, narrowing the gap to global leaders.
Which automotive customers and platforms have volume-qualified StarPower modules?
On the record: SiC MOSFET modules (Commercial use) at 800V EV platform OEMs (unnamed) for EV main motor controller and IGBT modules (Commercial use) at EV OEMs (unnamed) for EV main motor controller.
How much of the die, substrate, and epitaxy stack is internal, domestic-sourced, or imported?
Dependence on upstream SiC and IGBT wafer/substrate supply; specific automotive OEM concentration unclear. IGBT module competitiveness depends on die performance, thermal management, packaging, reliability, and automotive qualification.
Is SiC a commercial revenue driver or still mostly a roadmap/design-win story?
Named exposure so far: EV OEMs and Tier 1s, industrial drive makers, renewable-energy inverter suppliers, charging equipment vendors, rail, welding, UPS, and power-supply customers, Named customer claims should be shown only when source-specific; module qualification can be long and application-specific, and Midea.
