摘要: 介绍了新型软开关脉冲电容充电技术,其基本电路采用串联谐振拓扑,具备零电流开关、恒流充电、内在短路保护等优点。导出了该基本电路重要参数的计算公式。仿真了一个10kJ/s充电电源的波形。在重复频率较高、电容容量偏小时的不利情况下,在基本恒流电路的基础上,探讨了几种解决途径同时保留了恒流源的优点。Abstract: New type,soft-switching capacitor-charging techniques are introduced. Major parameters of basic constant-current charging circuit are calculated. Simulated and measured waveforms are given. Under the adverse condition of high repetition rate and small capacitance, methods of improving the performance of basic circuit are proposed while keeping the advantages of constant current charging.
