摘要: 设计了一种结构紧凑的陶瓷电容器型脉冲调制器,对其电路进行了理论计算，分析了主要参数对调制器输出波形的影响，并用PSpice软件建立电路模型进行验证，模拟结果与理论计算结果相符较好。该调制器能够产生上升前沿小于10 ns、脉宽30～40 ns、幅度为100～200 kV的可调高电压脉冲。该调制器用陶瓷电容器作为储能器件，用SF6作为绝缘介质，是一种无液体的脉冲调制器，具有结构紧凑、体积小、重量轻等特点。Abstract: A compact pulsed generator based on ceramic capacitor is designed. Its circuit is theoretically calculated and the effect of the main parameters on the output waveform is analyzed. A circuit model of the generator is established for validation with PSpice software, and the simulation results agree well with the calculated results. The generator can produce an adjustable high voltage pulse with the parameters of output voltage 100~200 kV, pulse width 30~40 ns and rise time less than 10 ns. The generator is a no-liquid pulsed generator with ceramic capacitors as the energy storage components and SF6 as insulated dielectric. It has characteristics of compact construction, small volume and light weight.
