Abstract

A 70 kVA/L air-cooled full-SiC three-phase inverter unit including power semiconductor modules, power capacitors, bus bars, gate drive circuits, a PWM wave generator and blower fans has been fabricated as a prototype for EV-use. SiC JFETs and SBDs of 1200 V were used. It has generated three-phase alternative power of 25 kVA to drive a 15 kW-class induction motor with only 190 W of dissipation. The module´s temperature was at most 90 ^oC.
