Abstract

In this study, fully soft switched boost converter with a new active snubber cell is proposed. This snubber cell provides zero voltage transition (ZVT) turn on and zero voltage switching (ZVS) turn off for the main switch. The auxiliary switch is turned on with zero current switching (ZCS) and turned off with ZVS. The current stress of the auxiliary switch is reduced significantly. Also, the main diode and all of auxiliary diodes are operating with SS. No semiconductor device has any additional voltage and/or current stresses. Theoretical analysis is verified with a 100 kHz and 1 kW experimental prototype.
