This paper presents detailed characterization of different 600 A, 600 V - 1200 V IGBTs suitable for electric propulsion applications. The IGBTs are characterized during conduction, turn-on and turn-off under hard and soft-switched conditions at 25 deg C and 125 deg C junction temperatures. The measured conduction voltage drop, turn-off loss and turn-on loss of IGBTs under hard and soft-switched conditions will be presented. A detailed investigation of various 600 A Dual IGBT modules has shown that current generation IGBT and diode silicon has better operating characteristics than earlier generations. Latest generation IGBTs have faster fall times, better tail current characteristics, and lower turn-off delays which subsequently reduce turn-off loss. The IGBTs also have much smaller dynamic saturation voltage spikes. However, the turn-off loss of recent generation of IGBTs under soft switching condition is still not significantly reduced at elevated temperature.
