Abstract :
A 4.5 kV-400A SiC-PiN diode and Si-IEGT hybrid pair module has been developed for realizing high switching frequency operations of medium-voltage power converters. The maximum switching frequency of the hybrid pair module is theoretically analyzed from viewpoints of cooling capacity of the heat sink and the minimum pulse width of a PWM signal. Operation tests of the hybrid pair module are implemented and 10 kHz operation has been successfully demonstrated.
