BorgWarner will provide a high-voltage silicon carbide inverter to an unnamed German automaker for implementation in its EVs. The BorgWarner 800 V SiC inverter with proprietary power switches provides a compact and efficient power module designed to deliver higher EV range and enhanced driving performance.
The inverter uses a scalable power switch for 800 V systems, allowing it to be optimized for a variety of customer applications at different power levels. The design builds on BorgWarner’s cooling technology, which enables a reduced semiconductor area. The system also offers greater durability and enhanced packaging thanks to its compact, patented power switch that is cooled on both sides and uses no wire bonds. The silicon IGBTs in the modular power switch have been replaced by SiC transistors. Because SiC has higher switching efficiency and fewer conduction losses, BorgWarner’s new inverter has reduced power losses of 40% to 70% as compared to silicon-based inverters, depending on the drive cycle.
“We are pleased to have won this SiC inverter contract and to enter the next stage of a long-standing cooperation with this manufacturer,” said Dr. Stefan Demmerle, BorgWarner President. “Our SiC inverter, with its new state-of-the-art power module, can be a game-changer for automakers since the new technology offers enhanced power density, proven performance, and long-term reliability.”
