Abstract
This paper proposes a new topology of soft-switching bidirectional converters family with ZVZCS switching capability. In this converter, the series LC is used to create resonance for soft-switching conditions. The proposed converter has a low current ripple, which causes to reduces the conduction losses, thus increasing efficiency. Due to the specific structure of the proposed converter, the voltage stress of switches is reduced. In this converter, the main inductor is used in the buck side to reduce the output current ripple and achieve continuous current. The proposed converter is examined and analyzed using theoretical relations in all operation modes and then compared with a series of conventional converters presented in this field so far. Finally, the proposed converter is simulated in PSCAD/EMTDC, and its performance is verified through simulation results.
