Abstract

In this paper, a novel dual-bridge series resonant converter is proposed. Compared with the conventional dual-bridge series resonant converter (DBSRC), the proposed converter improves the connection method of the primary side switches of transformer, and sets two series voltage equalizing capacitors to achieve voltage balance. The theoretical analysis and modeling of the proposed converter are carried out in this paper. The results show that compared with the conventional DBSRC, the proposed converter can reduce the voltage stress of the primary side switches to half, effectively reduce the switching loss of the primary side switches. This implies that the proposed converter can achieve higher efficiency as the switching frequency increases. However, its output power and energy density are lower than conventional DBSRC. At last, a 500 W simulation model is built, simulation model results verify the feasibility and advantages of the proposed converter.
