摘要

提出了一种基于相移控制的新型ZVZCS全桥DC-DC变换器。该变换器在不增加电流和电压应力的情况下，可以实现超前滞后开关的ZVS和滞后分支开关的ZCS。该变换器通过降低循环导通损耗和采用肖特基二极管实现高效率，特别是在高输入电压应用中。一台1kw的样机验证了理论分析。

A novel phase shift controlled ZVZCS full bridge DC-DC converter: analysis and design considerations

A novel ZVZCS full bridge DC-DC converter based on the phase shift control is proposed in this paper. The converter can achieve ZVS for leading lag switches and ZCS for lagging leg switches respectively without any increase both current and voltage stresses. This converter can achieve high efficiency by reducing the circulating conduction loss and employing schottky diodes, especially in high input voltage applications. A 1 kW prototype verified the theoretical analysis.
