摘要

This paper presents a new zero-voltage switching (ZVS) DC/DC converter with three resonant tanks for high input voltage and high load current applications. Two series half-bridge legs and two split capacitors in order to limit the voltage stress of active switches at a half of input voltage. These resonant circuits are operated by an interleaved PWM scheme. The output sides of these resonant circuits are connected in parallel to evenly distribute the input power, lessen current stresses on rectifier diodes and reduce copper losses of transformers. The ZVS turn-on through power switches and zero-current switching (ZCS) turn-off for rectifier diodes are accomplished through three series resonant tanks. Therefore, switching losses of MOSFETs and reverse recovery problem of rectifier diodes are reduced. The primary windings of two transformers are series-connected to balance the secondary winding currents. Finally, experiments based on a scale-down prototype are provided to verify the performance of the proposed converter.
