摘　　要：针对传统Marx发生器存在的时间常数大、输出效率低、输出参数单一等问题,通过优化SSBM(Solid-State Bipolar Marx)电容储能单元的全桥IGBT结构,设计了T-SCC(Two-Switches Capacitors Cells)脉冲发生器,并且根据高频高压下功率IGBT呈现容性负载的特性,提出一种寄生参数动态模型。对寄生参数动态模型的仿真实验结果表明T-SCC脉冲发生器能输出μs级上升沿的双极性脉冲电压,提高了系统输出电压和寄生电容充放电速度,达到了脉冲上升沿压缩的目的。To tackle the problems of the traditional Marx generator,such as large time constant,low output efficien-cy and single output parameters,the T-SCC（Two-Switches Capacitors Cells）pulse generator is designed through thestructure optimization of the full bridge IGBT of the SSBM（Solid-State Bipolar Marx）pulse generator. At the sametime,according to the capacitive load characteristics of the IGBT,a dynamic model of parasitic parameter is pro-posed. Simulation experiments on the dynamic model of parasitic parameters show that the T-SCC pulse generatorcan output bipolar pulse voltage with microsecond rising edge,and can improve the system output voltage and dis-charge rate of the parasitic capacitance,reaching the purpose of compressing the rising edge of the pulse.
