Abstract :
The emitter turn-off thyristor (ETO) is a GTO-MOSFET hybrid power semiconductor device that turns off the GTO under the unity turn-off gain condition. This paper analyzes the failure mechanism in the snubberless turn-off of the ETO and proposes solutions that extend the snubberless switching capability to the theoretical limitation of the device. Theoretical analysis and experimental results are presented
