摘要：
In this paper, a novel zero voltage switching (ZVS) bi-directional DC/DC converter is presented. The proposed converter is composed of two symmetrical topologies. With the help of inductor and the transformer leakage inductance, ZVS is realized for all switches in the whole load range. What's more, the diode reverse recovery is also diminished with ZCS and the corporation of a designed pulse-width modulation control. These measures reduce switching losses, voltage and current stresses and electromagnetic interference (EMI). In the theoretical analysis, the switching cycle as well as the operation principle of soft switching is described in detail. Experimental results of 500W prototype prove all the switches of the proposed converter can operate in the ZVS condition without requiring any additional circuit components over a wide range.
