BorgWarner to integrate STMicroelectronics’ SiC tech in traction inverters for Volvo EVs

Global semiconductor firm STMicroelectronics is to supply BorgWarner with its latest third- generation 750V silicon carbide (SiC) power MOSFETs dice for BorgWarner’s Viper-based power module. This power module is used in BorgWarner’s traction inverter platforms for several current and future Volvo Cars electric vehicles.

“This collaboration will give Volvo Cars the opportunity to further increase the attractiveness of our electrical vehicles with longer range and faster charging. It will also support us on our journey towards being fully electric by 2030 and strengthen our increased vertical integration and our control of critical components," said Javier Varela, Chief Operating Officer & Deputy CEO, Volvo Cars.

“BorgWarner is pleased to partner with ST to supply our longstanding customer Volvo Cars with inverters for their next generation of BEV platforms,” says Stefan Demmerle, Vice President of BorgWarner Inc. and President and General Manager, PowerDrive Systems.

To fully leverage the performance of ST’s SiC MOSFET dice, BorgWarner collaborated closely with ST’s technical team to match their die with BorgWarner’s Viper power switch, thereby maximising inverter performance and delivering a compact and cost-effective architecture. The collaboration between the companies provides the high-volume capability that is required by the quickly growing EV market.

“Our collaboration with BorgWarner, a leading global automotive supplier in electrification, will enable Volvo Cars to offer their customers superior vehicle performance and range,” says Marco Monti, President, Automotive and Discrete Group, STMicroelectronics.

ST’s high-volume STPOWER SiC products are manufactured in its fabs in Italy, and Singapore, with advanced packaging and testing at its back-end facilities in Morocco and China.
