Abstract In order to solve the problem of oscillation caused by the MOSFET output capacitance in the after flow stage of the CLLLC resonant converter,based on the analysis of the effect caused by the output capacitance on the operation principle and the working characteristics,an optimized design method is proposed to maintain soft-switching and alleviate oscillation.In addition,this paper uses hysteresis burst-mode control to solve the problem of the high output voltage at light load condition,which is caused by the output capacitance.This control scheme can regulate the output voltage to the rated value,and reduce the losses at light load condition.Finally,a prototype with 400 V/48 V DC buses and 1 kW power rating is built.The experimental results verify the performance of the proposed design method and control scheme.
