초록

In this paper, For achieving the high gain and resonant characteristics in both of the power flow directions, a bidirectional resonant dc-dc converter with auxiliary switches is proposed. Auxiliary switches are connected in the primary and secondary side of the bidirectional resonant dc-dc converter, respectively. A 800W prototype bidirectional resonant dc-dc converter for interfacing the 400V DC buses in the energy storage system is built and tested to verify the validity and applicability of this proposed converter.
