Abstract
Based on full-bridge phase-shifted zero voltage and zero current switching (FB-PS-ZVZCS) PWM converter, this paper presents the design procedure of a 6 kW battery charger. In the converter, one blocking capacitor and two diodes are added in the primary side of the transformer to realize ZVS for the leading-leg and ZCS for the lagging-leg. The very detailed analysis of the operation principles is proposed. According to the results, some simplification works are done and the design procedure of the main parameters, including the value of the switches snubber capacitor, the blocking capacitor and the delay time between gates drive signals, also is drown. Finally, a 6 kW battery charger prototype is built. The simulation and experiment results verify the parameters as well as the proposed design procedure.
