摘要
为了满足某脱离电网的应用需求,研究了一种基于爆磁压缩发生器的紧凑脉冲功率源。该脉冲功率源设计目标是对等效电容为65pF的电容负载快速充电至数百kV。考虑到爆磁压缩发生器与负载之间的阻抗匹配,该脉冲功率源采用了一种主要由电爆炸断路开关、脉冲变压器和中间储能电容器组成的脉冲调制模块。详细介绍了该脉冲功率源的具体设计和实验研究,并对实验结果进行了分析,在此基础上讨论了下一步可能的改进优化。研究结果表明,利用该脉冲源对电容负载充电电压达到了-352kV,电压上升时间约10ns。
This paper introduces a single-shot compact pulsed power source(PPS)based on an explosively driven flux compression generator(FCG)for some off-grid applications.The PPS was designed to rapidly charge a capacitive load of 65 pF to hundreds of kilo volts.Considering the impedance mismatch between the FCG and the load,apower conditioning module mainly consisting of an intermediate capacitor,an electro-explosive opening switch(EEOS)and an air-cored transformer was employed.This paper presents the design and experimental results in detail.Besides,it analyzes the experimental results and discusses the possible improvements in future.It is indicated that the capacitive load was successfully charged to!352 kV with a rising time of about 10 ns.
