针对脉冲功率系统开关触发需求,设计了一种重复频率Marx发生器，介绍了其基本工作原理及其主要性能指标。发生器采用单极性充电和同轴结构设计，脉冲输出为高压电缆形式，在75 Ω匹配负载上获得了高于200 kV的脉冲输出，脉冲宽度大于90 ns，工作模式可单次到10 Hz重复频率运行，脉冲上升时间小于10 ns，系统抖动小于20.1 ns。

One Marx generator for triggering switch of pulse power system is developed. The basic principle and main parameters are specified. The coaxial structure and resistor type design are adopted. The output parameters of generator on matched load, 75 Ω, are higher than 200 kV voltage amplitude, more than 90ns pulse width, single to 10 Hz repetition operation, less than 10 ns rising time, less than 20.1 ns time jitter.
