Abstract :
Possibility of a 10 kHz switching frequency operation of a 4.5kV-400A SiC-PiN diode and Si-IEGT hybrid pair module has been investigated to drastically increase the switching frequency of medium-voltage power converters. For this purpose, the relation among the minimum pulsed width of the PWM signal, the modulation index, and the maximum switching frequency is analyzed based on the switching characteristics of the hybrid pair module. The analyzed data show that the 10 kHz switching frequency could be available with the hybrid pair module.
