摘要：
In this paper, a novel soft-switching bidirectional DC-DC converter based on coupled inductors is suggested. This converter includes four switches and a pair of coupled inductors and can achieve high voltage conversion ratio in step-up/step-down modes. Employing the interleaved technique reduces input current ripple and thereby increases the efficiency of the converter. The ZVS turn-on characteristic is obtained in both boost and buck directions for all converter switches. The uncomplicated and efficient control, as well as operation under proper duty cycle, are the other advantages of the suggested converter. A 500W prototype 36V/400V is simulated to validate theoretical conclusions.
