摘要

摘要: 针对高功率脉冲驱动源的重复频率充电需求，基于全桥串联谐振恒流充电技术，研制了一台紧凑型串联谐振高压电容充电电源，平均充电功率12 kW。该电源采用超级电容器预储能和全桥串联谐振电路，大幅降低了场地供电需求，结合模块化集成设计，实现了一体化、便携式设计。针对脉冲驱动源工作需求，分析了全桥串联谐振电路的基本原理和工作过程，给出了电路参数设计方法和Pspice电路仿真结果，利用该电源对等效电容量为0.3 μF的脉冲驱动源进行了充电测试，实现了45 ms内充电60 kV以上，实验结果表明, 其输出能力满足PFL-Marx脉冲驱动源的20 Hz重频充电需求。

Abstract: A compact series resonant high voltage capacitor charging power supply with an average charging power of 12 kW is developed based on full bridge series resonant constant current charging technology to meet the repetitive charging requirement of a high power pulsed generator. The power supply uses supercapacitor pre-storage and full-bridge series resonant circuit, which greatly reduces the demand for environmental power supply. Combining with modular integrated design, the integrated and portable design is realized. According to the working requirement of the pulsed power generator, this paper analyses the basic principle and working process of the full bridge series resonant circuit, presents the design method of circuit parameters and the circuit simulation results. The power supply developed was used to charge a PFL-Marx pulsed power generator with the equivalent capacitance of 0.3 μF, the charging voltage was more than 60 kV in 45 ms. The experimental results show that its output capacity meets 20 Hz repetitive charging requirement of the PFL-Marx pulsed power generator.
