US silicon carbide (SiC) power products producer Wolfspeed has launched a 900V 10mΩ SiC metal–oxide–semiconductor field-effect transistor (MOSFET) that runs at 25C and reduces EV drivetrain inverter losses by 78%. Wolfspeed said its chip functions well in harsh environments, and John Palmour, CTO, added: "Our devices can now support significant efficiency improvements… in EV drivetrains". The company recently supplied Ford with a full-SiC, 400A power module based on the 900V version.
