利用1:1变压器和脉冲频率调制控制提高双向DC-DC变换器的功率转换效率

This paper proposes a circuit structure of bidirectional dc–dc converter. This structure uses two switches, two capacitors, a 1:1 transformer, and a control circuit for pulse-frequency modulation. The windings of the transformer are connected in a series-aiding configuration to reduce current ripples and to increase power conversion efficiency $\eta _{e}$. The capacitors and the leakage inductance...
