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.
