摘要: 层叠Blumlein脉冲发生器具有灵活紧凑的优点，但由于开关隔离问题没有得到广泛运用。设计了一种集成隔离全固态层叠Blumlein脉冲发生器，利用4绕组共模电感为脉冲形成网络充电、驱动供电和高电压隔离的器件，解决了半导体开关应用于层叠Blumlein脉冲发生器的问题。首先介绍了隔离的原理，设计了包含共模电感和同步光触发隔离组件，以及基于IGBT开关阵列的Blumlein脉冲形成网络，分析了层叠Blumlein脉冲发生器的充放电过程；其次，对设计的Blumlein脉冲形成网络与层叠Blumlein脉冲发生器进行电路仿真；搭建了8级层叠Blumlein脉冲发生器，在匹配负载上实验得到电压30.0 kV、电流604 A、脉宽237 ns的方波脉冲。

Abstract: Stacked Blumlein pulse generators have the advantages of being flexible and compact, however, switch isolation issue hinders its applications. In this paper, an all-solid-state stacked Blumlein pulse generator is designed. A 4-winding common-mode inductor is used for charging the pulse-forming network, supplying driver circuit and isolating high-voltage. Firstly, the principle of isolation is analysed, an isolated trigger assembly containing common mode inductor and synchronous optical trigger is designed, the charging and discharging process of the stacked Blumlein pulse generator is analysed, and a Blumlein pulse forming network based on IGBT switch arrays is designed; secondly, simulation is carried out on the designed Blumlein pulse forming network and stacked Blumlein pulse generator, and 8-winding common mode inductors are used as the pulse forming network to drive the power supply and high voltage isolation device. Ultimately, an 8-stage stacked Blumlein pulse generator experiment was carried out, and a square wave pulse with a voltage of 30.0 kV, a current of 604 A, and a pulse width of 237 ns was obtained on a matched load.-
