摘　　要：在电压大范围变化条件下,针对纯电容负载介绍了串联负载谐振电路的工作原理、恒流特性以及软开关工作方式对高压电容充电品质的影响.在高频高压情况下,分析了以低压方式解决高压问题的多模块串联均压的典型电路结构,并讨论了变压器分布电容和漏感对充电的影响.实现了由直流48V供电,输出为10kV的高压电容恒流充电\电源.This paper presents the working theory and constant average charging current characteristic from zero volts to maximum voltage of series load resonant circuit when the load is capacitive.And,the influence of the soft switch model for charging quality of high voltage charger is also given.In the case of high voltage and high frequency,in order to solve the problem resulted from high voltage,typical series-module structures are used to average output voltage.Finally,by analyzing leakage inductance and distrib...
