Wolfspeed’s 1200V SiC MOSFETs to be adopted by Shanghai’s ZINSIGHT

Wolfspeed Inc of Durham, NC, USA says that its 1200V silicon carbide MOSFETs are to be used by ZINSIGHT Technology (Shanghai) Co Ltd – which focuses on electrical machine drive and systems based on SiC – in its advanced motor controller for ultra-high-speed air compressors in fuel cell vehicle (FCV) engines.

Consumer demand for zero-emission vehicles such as battery-electric vehicles (BEVs) and FCVs is expected to increase over the next decade as automakers and government entities shift focus away from production of internal combustion engine vehicles for a cleaner and more sustainable future. The use of silicon carbide in BEVs and FCVs results in significant cost savings, while high-efficiency power modules enable lower energy losses and higher range, says Wolfspeed.

“The air compressor is one of the most critical components in FCV engines, affecting both efficiency and volume,” says ZINSIGHT’s CEO Dr Shi Jingkui. “We partnered with Wolfspeed to harness its leadership in silicon carbide and ensure our technologies deliver best-in-class performance in speed, performance, efficiency, reliability and electromagnetic compatibility (EMC).”

Using Wolfspeed’s 1200V silicon carbide MOSFETs, ZINSIGHT developed an ultra-high-speed motor controller for use in FCV air compressors. The 35kW HS35 solution is said to provide enhanced efficiency and energy production, achieving more precise motor control over the entire FCV speed range.

“This collaboration further diversifies our automotive pipeline as we bring silicon carbide technology to fuel cell vehicles,” says Jay Cameron, senior VP & general manager for Wolfspeed Power. “Wolfspeed silicon carbide enables our customers to provide best-in-class efficiency as they help automakers lead the transition to a more sustainable future.”
