This paper presents the design and operation characteristics of a solid-state high voltage pulse generator. Its primary utilization is aimed at triggering a gaseous spark gap with high repeatability. Specifically, the trigger generator is designed to achieve a risetime on the order of 0.1 kV/ns to trigger the first stage, trigatron spark gap of a 10-stage, 500 kV Marx generator. The major design components are comprised of a 60 W constant current DC-DC converter for high voltage charging, a single 4 kV thyristor, a step-up pulse transformer, and magnetic switch for pulse steepening. A risetime of <30 ns and pulse magnitude of 4 kV is achieved matching the simulated performance of the design.
本文介绍了一种固态高压脉冲发生器的设计和运行特性。其主要用途是高重复性地触发气体火花间隙。具体而言，触发发生器的设计旨在实现约0.1 kV/ns的上升时间，以触发10级、500 kV马克思发生器第一级的触发管火花间隙。主要设计组件包括用于高压充电的60 W恒流DC-DC转换器、单个4 kV晶闸管、升压脉冲变压器以及用于脉冲陡化的磁开关。实现了<30 ns的上升时间和4 kV的脉冲幅度，与设计的模拟性能相匹配。
