The purpose of this paper is to improve power conversion efficiency of three-phase soft-switching voltage-source inverter with an auxiliary resonant de link (ARDCL) snubber circuit Firstly, the operating principle of ARDCL snubber circuit is described. Secondly, this paper proposes an effective generation method of zero voltage vector for three-phase voltage-source soft-switching inverter m which power losses in the ARDCL snubber circuit can be reduced. In particular, zero voltage holding interval in the inverter DC busline can be controlled due to the new generation scheme of zero voltage vector Thirdly, a simulator for power loss analysis, which includes switching and conduction loss characteristics based on actual system, is developed The validity of developed simulator is proved with experimental results Finally, power efficiency of three-phase inverter is estimated according to high carrier frequency by using the simulator
