An interleaved pulse-width modulation (PWM) zero voltage switching (ZVS) converter is presented in this paper. Two converter modules with interleaved PWM scheme are used in the proposed circuit to achieve load current sharing and reduce the ripple currents on the input and output capacitors such that the size of the output choke and capacitor are reduced. For each module, two buck-type dc-dc converters with only two switches are used to reduce the current rating of transformer winding and share the load current. Two buck-type converters in each module use the same switching devices to regulate the output voltage. The ZVS turn-on of the switches is achieved by utilizing the transformer leakage inductance and output capacitance of switches. Thus the switching losses of the proposed converter are reduced. Experiments based on a 660W prototype are provided to verify the theoretical analysis and the effectiveness of the proposed converter.
