Performance Improvement for Plug-In Reverse Conducting IGBTs through Gate-Voltage Observation

Abstract

While driving a plug-in RC-IGBT, the performance outcome can be significantly improved by adapting the turn-OFF process. Hereby, the observation of the characteristic gate-voltage behavior allows the distinction between IGBT and diode turn-OFF. Latter can be easily manipulated in order to utilize the full potential of the inverter locking time.
