250 kV，1 MHz重复率方波三脉冲源

 阐述了一种新的实现高功率高重复率方波脉冲源的技术途径，利用高压快恢复整流硅堆把三个独立的方波脉冲合成为一个MHz重复率的方波三脉冲。通过合理的串并联设计，可以提高硅堆在高频脉冲下的反向耐压，并使硅堆通过的正向脉冲电流达到kA量级。方波三脉冲源输出指标达到了电压250 kV，脉冲电流10 kA，峰值功率2.5 GW，重复率1 MHz，脉冲上升时间约40 ns，脉冲平顶宽度50 ns。

A 250 kV,1 MHz repetition rate square triple-pulses generator

This paper summarizes a novel method for high-power high repetition rate square pulse generator. By using high voltage rectifier diodes, three single square pulses are combined to form an MHz level repetition rate square tripl-pulse. Suitable connection design in parallel and in series lets the rectifier diodes stand high reverse voltage in high frequency and elevates rectified pulse current to kiloampere level. The square triple-pulses generator has an output voltage up to 250 kV, a pulsed current of 10 kA, pulse power of 2.5 GW, a repetition rate of 1 MHz, a pulse risetime of 40 ns, and a pulse flat top of 50 ns.
