A Novel Auxiliary Resonant Commutated Pole Soft-switching Inverter

In order to reduce the number of auxiliary inductors and improve the load adaptability of the auxiliary resonant commutation pole soft-switching inverter(ARCP) inverter, a novel auxiliary resonant commutation pole soft-switching inverter is proposed, which is characterized by simple structure and low power loss. The proposed inverter only contains two auxiliary commutation inductors. And the commutation processes of the two-phase main switches are simultaneously assisted by the same auxiliary inductor. All main switches in the proposed inverter can achieve zero voltage switching, and all auxiliary switches can achieve zero current switching. The proposed inverter has a simpler structure, higher efficiency and better load adaptability than the ARCP inverter. The effectiveness of the proposed inverter is verified by simulation and the experiment results.
