摘　　要：根据重复频率脉冲功率系统中大功率开关器件氢闸流管的触发原理,针对选用的VE4141氢闸流管的触发要求,设计了输出频率达到5 kHz的氢闸流管触发系统,可以接收光信号和电压信号触发.采用快前沿MOSFET开关产生两路触发脉冲,一路为预触发脉冲,一路为主触发脉冲.预触发脉冲的输出幅度为500～1000 V,主触发脉冲的幅度为1000～2000 V,两路脉冲之间延时500 ns可调.该触发器可通过部分改动应用于其他的大功率开关器件的触发系统.A trigger device is designed for the hydrogen thyratron VE4141according to the trigger method of hydrogen thyratrons used in the repetitive pulse-power system,which can output trigger pulses of repetition rate up to 10kHz.In addition,it can receive optical and electric trigger signals.The pre-trigger pulse and main-trigger pulse are produced by fast-edge MOSFET switch.The former output amplitude is 500-1000V;the latter amplitude is 1000-2000V.Pulse delay time is about 500ns and can be adjustable between the two trigger pulses.The trigger device can be easily applied to other high-power switches and pulse-power systems by adjusting some electronic components.
