多路高压触发源抗干扰的新方法

A New Method for Anti Disturbance in a Multi Channel High Voltage Trigger Generator

提出了一种多路高压触发源抗干扰的新方法，它的特点是各触发电路中的储能电容器并非同时处于充好电的准备状态，而是按预定的实验时序充电并立即放电。因此，当某一火花开关被触发放电并产生电磁干扰，导致其他各路中的开关元件（如晶闸管）误动作时，这几路也不会输出高压触发脉冲（由于它们的储能电容器上电压为０）。该方法被用于电感隔离型重复频率ＭＡＲＸ发生器的触发系统中，取得了很好的结果。

A new method for anti disturbance in a multi channel high voltage trigger generator was developed The energy storage capacitor in every channel is charged and then immediately discharged one by one channel in order of experiment instead of all the capacitors being charged at a same time and then waiting for trigger When a spark gap is triggered by one channel and produces electromagnetic disturbance leading to the misoperations of switching elements(such as pulsed thyristors) in the other channels,these channels will not give out trigger pulses due to no voltage in their energy storage capacitors The method was satisfactorily used in the trigger system of a repetitive Marx generator with inductively isolated capacitor stages
