High-Power Converters with High Switching Frequency Operation using SiC-PiN Diodes and Si-IEGTs

摘要：

High-frequency switching operations are required in medium-voltage power converters to realize compact power converter systems. High-voltage hybrid pair modules using SiC-PiN diodes and Si-IEGT are expected to increase the switching frequency. In this work, 4.5 kV-400 A SiC-PiN diode and Si-IEGT hybrid pair modules have been developed. Hard driving is applied to the hybrid pair module for low switching losses and stable series voltage balance between two seriesconnected modules. Operation tests of developed hybrid pair modules with the switching frequency of 4 kHz have been carried out in a 1 MVA class prototype power converter.
