摘　　要：为了对电容重复频率且高能量转换效率地充电,开展了全桥串联谐振充电电源的理论设计。通过数值解析的方法获得谐振电感、电容、功率器件耐压与通流、电源功率、脉冲变压器伏秒数等参数,通过数值模拟的方法获得脉冲变压器励磁电感参数,以基于Pspice的全电路仿真验证设计参数的合理性。仿真结果表明为了实现对110 nF电容1 kHz重频充电,在初级电压为1.2 kV和谐振参数为33 kHz时,谐振电感、电容应分别为625 nH,37μF,脉冲变压器伏秒数、励磁电感至少分别应为45 mVs、1 mH,功率器件峰值电流约300 A。Abstract： It is necessary to charge capacitor with high repetitive rate and high energy transfer efficiency that utilizing full bridge series resonant circuit. Calculating series resonant inductance, resonant capacitance, hold-off voltage and peak conductive current of power transfer switches, total power, and volt second of magnetic core; Getting excitation inductance of pulse transformer and validating these parameters by circuit simulation. Results show that resonant inductance and capacitance were 625 nH and 37uF, respectively, volt second and excitation inductance were 45 mVs and lmH, respectively, peak current of power components was about 300 A, to charge 110 nF with 1 kHz rate when primary power voltage and resonant frequency were 1.2 kV and 33 kHz, respectively.
