一种基于谐振网络的高增益宽范围软开关双向DC-DC变换器

A soft-switching bidirectional dc–dc converter (BDC) is proposed for high voltage gain and wide range applications. A resonant network composed of a coupled inductor and resonant capacitors is integrated into an interleaved buck/boost BDC to achieve high voltage gain. Meanwhile, the resonant network can control the circulating leakage inductor's energy and suppress the change of the resonant curre...
