摘要:A novel zero-voltage-switching (ZVS) bidirectional dc/dc converter for energy storage system is proposed in this paper. The primary side is the improved push-pull topology adding one switch to achieve ZVS and the secondary side is a full-bridge topology. Compared with the conventional dual-active-bridge (DAB) dc/dc converter, the proposed converter applies a three-switch topology substituting for the full-bridge structure in the low-voltage side of transformer with seven switches in all. With minimum switch, the cost of the driving circuit can also be saved and the stability of the whole system can be better guaranteed. Most of all, the proposed converter can realize the advantages of DAB, such as bidirectional power transmission and ZVS. Besides, it has no increase in power losses and transformer volume reaching relatively the same effect of the DAB. The operation principles, comparative analysis, design, and control strategy are presented in detail. A 500-W laboratory prototype is built to verify the theoretical analysis and demonstrate the validity of the converter.
