A new interleaved flyback converter topology is proposed. The converter utilizes the resonance between the leakage inductance of transformer, parallel capacitance of switches and clamp capacitor to realize Zero Voltage Switching (ZVS). The voltage spike is eliminated and the voltage stress can be reduced when the switch is turned off. The converter has the advantages of simple topology, soft-switching, small output current ripple and simple control. The detailed operation principle and the condition of soft switching are presented. Finally, the analysis above is verified by simulation and experiment.
