Abstract

Device side soft-switching inverters provide a desired zero-current switching (ZCS) turn-off and zero-voltage switching (ZVS) turn-on of the switching devices with the resonance at the device side. However, ZCS and ZVS cannot be realized with the same topology. A novel soft-switching inverter with both ZCS and ZVS features is proposed in this paper. The advantages of the proposed inverter topology are that all the main and auxiliary switches can be turned off with ZCS and can be turned on with ZVS. The principles of operation have been investigated with equivalent circuits at different operation modes for both ZCS and ZVS under different load current directions. Simulation with Saber gives the results that agree with the theoretical analyses
