Frequently Asked Questions
What is the IGBT market outlook in China?
China IGBT market reached RMB 30B+ in 2025 growing 20%+ annually. EV applications are the largest segment at 45%, followed by industrial drives (25%), renewable energy (15%), and consumer electronics (15%). Domestic IGBT share is expected to reach 50%+ by 2027 as BYD Semi, StarPower and CRRC Times expand capacity and close performance gaps with Infineon and Mitsubishi Electric.
How does SiC compare to silicon IGBT?
SiC MOSFETs offer 50% lower switching losses, 30% higher power density, and 200C higher operating temperature than silicon IGBTs. This enables smaller, lighter, more efficient EV inverters. However, SiC devices cost 3-5x more than silicon IGBTs currently. Chinese companies including BYD Semi and San'an are aggressively expanding SiC capacity to reduce costs, targeting price parity with silicon by 2028-2030.
What is GaN power electronics?
Gallium nitride (GaN) power devices operate at even higher frequencies than SiC, enabling ultra-compact chargers and power adapters. Navitas (US with China operations) and Innoscience (Chinese startup) produce GaN power ICs for consumer fast chargers up to 300W. China GaN power market is growing rapidly but remains smaller than IGBT/SiC, focused on consumer electronics and data center power supplies.
What is China's market position in SiC power devices?
China accounts for over 40% of global SiC substrate production, with companies like TankeBlue and SICC producing 6-inch conducting and semi-insulating substrates. Domestic SiC MOSFET and diode production has reached 1,200V-3,300V voltage ratings, primarily used in new energy vehicles and industrial power supplies.
How are Chinese power electronics companies competing in EV inverters?
BYD, CRRC Times Electric, and Bosch (China) supply IGBT and SiC-based inverters to domestic EV manufacturers. BYD's Blade inverter platform using self-produced IGBT chips has achieved 98% efficiency, reducing energy losses and extending vehicle range by approximately 5%.
