US silicon carbide ( SiC ) power module , 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 claims its chip functions well in harsh environments , and John Palmour , CTO , added : " Our devices can now support significant efficiency improvements … in EV drivetrains " . The module, designed and produced by Wolfspeed, contains four MOSFETs connected in parallel to achieved a remarkable 2.5mΩ Rds(on). The company recently supplied Ford with a full - SiC , 400A power module based on the 900V chip .
