摘要

主要介绍一种为大电流开关点火的精密长延迟纳秒高压脉冲源系统的研制过程.该系统采取低压固体电路与大小氢闸管电路的配合、合理配置并较好地解决了精密长延迟和高压脉冲输出时低延迟时间晃动的难点.该源具有晃动小和可调的精密长时间延迟以及上升时间小、幅度大的脉冲输出波形并且具有抗强电干扰等特性.%A precision long delay ns grade high - voltage pulse generator used for high voltage current switch igniting was introduced. The pulse generator isused solid state driving circuits,hydrogen thyratron switch and its supply circuits,by reasonable designing and solving the problem of long - time delay output pulse jitter and anti - electromagnetic interference, it can produce pulse with low - jitter and fast rise - time high - voltage, and can reach highly anti -electromagnetic interference performance.
