脉冲功率氢闸流管重复频率触发 pulse power hydrogen thyratron repetition-rate trigger

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。

Abstract

A trigger device is designed for the hydrogen thyratron VE4141 according to the trigger method of hydrogen thyratrons used in the repetitive pulse-power system, which can output trigger pulses of repetition rate up to 10 kHz. 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 500-1000 V; the latter amplitude is 1000-2000 V. Pulse delay time is about 500 ns 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.
