摘要: 研究了一种结构紧凑型的多级层叠Blumlein纳秒脉冲形成线，从理论上分析了放电时回路各分布参数对层叠Blumlein脉冲形成线输出电压的影响，并利用PSpice模拟验证了各分布参数对层叠Blumlein脉冲形成线输出结果的影响，发现开关的导通电阻是制约输出电压幅值的主要因素，开关的分布电感对输出波形的影响大于负载分布电感的影响，基于时域有限差分法原理，利用XFDTD软件模拟了两级层叠Blumlein线的电磁耦合效应。开展了多级层叠Blumlein脉冲形成线实验，结果表明，基于陶瓷固态传输线和GaAs光导开关的层叠Blumlein脉冲形成线能够实现输出电压叠加，可用于产生ns量级脉宽的脉冲高压。

Abstract: A kind of compact stacked Blumlein nano-second pulse forming lines was studied in this paper, and the effect of circuits distribution parameter on output voltage of 2-staged stacked Blumlein pulse forming lines (PFLs) was analyzed and simulated by PSpice. The results show that the switchs on-resistance reduces the amplitude of output voltage, and the influence of the switchs inductance is greater than the influence of the loads inductance. The electromagnetic coupling effect of 2-stage Blumlein PFLs with different stacked structures was simulated by using XFDTD based on the principle of finite difference time domain method. The experiments of multi-stage stacked Blumlein PFLs were performed. The results show that, stacked Blumlein PFLs, based on ceramic solid-state transmission lines and GaAs photoconductive switches, achieve the superposition of output voltage, which could generate a nano-second high-voltage pulse. -
