一种具有低电压应力的高变比高效率双向DC-DC变换器

A dc–dc converter is proposed to achieve a high voltage conversion ratio for bidirectional power flow applications. The nonisolated topology is optimally designed to integrate both the switched capacitor and coupled inductor techniques for high efficiency. The windings of the coupled inductor are stacked at the low voltage source, which transfers any leakage energy of the coupled inductor directly...
