摘　　要：根据100kV Mini-Marx脉冲发生器对触发源的技术要求,设计了一种基于VE4141型氢闸流管气体开关器件的高压脉冲触发源。该触发源系统输出高压脉冲幅度达到0～30kV、脉冲前沿小于15ns、脉冲宽度大于500ns,不仅可以接收光、电和手动信号触发,而且还可以通过接口来控制调整100kV Mini-Marx发生器的充电电压以及电压显示。采用固态IGBT半导体开关器件产生预触发和主触发脉冲,控制气体开关氢闸流管VE4141瞬间导通放电输出高压脉冲信号,触发后级Mini-Marx脉冲发生器产生不小于100kV的高压脉冲。A trigger is designed based on VE4141 thyratron for the 100 kV Mini-Marx generator. The trigger meets the fol- lowing design specifications： pulse voltage is up to 30 kV, falling time is less than 15 ns, pulse width is more than 500 ns. It can receive optical signal, electric signal and manual signal to trigger. Charge voltage can be adjusted and displayed by the control plane. Pre-trigger and trigger signals are received through an IGBT drive circuit, and are used to control the VE4141 thyratron to discharge and get a high voltage pulsed signal to trigger the 100 kV Mini-Marx generator.
