摘要: 在多路并联运行的电容储能型脉冲功率源中，为实现初级储能气体开关和脉冲形成主开关的同步，需要多组延时可调、每组多路输出的快前沿高电压脉冲来分别触发，为此研制了一套快响应低抖动100 kV快前沿电脉冲触发系统。该系统由同步机DG535和多组电脉冲放大单元组成，各组放大单元输出脉冲的延迟时间可调，延时步长由DG535设定，每组最短延时时间约为305 ns，抖动2 ns，可同时输出多路触发脉冲，在高阻负载上幅值可达180 kV，当输出信号为4路时，上升时间10 ns，当输出信号为8路时，上升时间15 ns。Abstract: For a pulsed power source which consists of multi-module and works in parallel, many gas spark switches in primary capacitor storage units and high voltage pulse-formed gas switches should be synchronized by triggering generator system. A multi-module and multi-output triggering generator system with high voltage, fast rise time, low jitter is developed. The system includes a multi-function synchronous signal generator DG535 and several step-by-step pulse amplifier units in series. The amplifier is based on hydrogen thyratron and spark gaps. Each amplifier unit can output multi-pulse at the same time, and when the output is 4-pulses or 8-pulses, the rise time is about 10 ns or 15 ns. The minimum delay time of the system is 305 ns and the jitter is about 2 ns. The maximum output voltage on
