Abstract

A new soft-switching technique for the bridge converters is presented to provide soft-switching transitions for the power switches and thus to reduce the power losses, component stresses, and noise generation. The proposed technique utilizes parallel-quasi-resonant circuit to create a zero-voltage-switching opportunity for the inverter switches, without high switch voltage and current stresses. The overall efficiency will approach 95%. The operation of the circuit is explained. The results of PSpice simulation are also shown to verify the operation principles
