摘要：
In this paper, the series resonant three-phase dual active bridge DC-DC converter based on the Y-Δ connection of the transformer is studied. First, the operation principle is analyzed in detail, and the inductor current, output power, and soft switching conditions are derived. Secondly, the secondary circuit of the transformer is reflected to the primary side, which greatly simplifies the circuit model of the converter. On this basis, the circuit parameters selection and hardware design are carried out. Then, by analyzing the power losses of transformer, inductor and switches, the total power loss model of series resonant three-phase DAB converter is established. Finally, a 500 W experimental prototype is designed to verify the accuracy of theoretical analysis and power loss model. © 2022, Solar Energy Periodical Office Co., Ltd. All right reserved.
