Abstract :
A fully integrated Silicon Carbide (SiC) JFET/SBD based six-pack power module is designed and developed. The stability of the module assembly processes are confirmed with thermal shock test of -40 to +200 °C temperature cycling. A three phase inverter with the SiC power module is designed and developed for the EV/HEV applications. The liquid cooled inverter is 22.9 × 22.4 × 7.1 cubic centimeters in volume (~8.35kW/L) and 3.53 kilograms in weight (~8.5kW/kg). A conversion efficiency of 98.5% is achieved at 10 kHz switching frequency and 10 kW. The inverter is evaluated with coolant temperature up to 95 °C successfully.
