| 摘 要： | 采用平板线加载的陶瓷电容型脉冲形成网络（PFN）构成了单开关调制的层叠Blumlein线发生器。采用传输线理论对短路寄生传输线的短路特性进行了理论分析，结果表明，短路寄生传输线的阻抗可以等效为耦合电感在主传输线的放电频率下产生的感抗。Pspice软件模拟表明，层叠线Blumlein线的电压叠加效率随耦合电感增加而增加。提出了一种磁环增感方法，在4级层叠Blumlein线上实现了3.1倍的脉冲电压叠加。

| Abstract: | This paper presents a pulse forming network(PFN) stacked Blumlein pulse generator commutated by a single switch, in which the PFN is composed of ceramic capacitors and plate conductors. The shorted discharging characteristic of the shorted parasitic transmission line was analyzed in theory. Results show that the shorted parasitic transmission line could be replaced by a shorted inductor. Equivalent circuit models were simulated using Pspice code to compare the effect of the shorted parasitic transmission line with that of the shorted inductor. Simulation results show that the increase in the inductance of the shorted parasitic transmission line could improve the voltage efficiency. A four-stage stacked Blumlein pulse generator with magnetic cores was designed to increase the shorted inductance. Its voltage gain reaches 3.1 on the matched load. |
