Abstract

In this article, we describe a rectangular pulse generator, consisting of a polymer-film switch, a tri-plate transmission line, and parallel post-shaped ceramic resistor load, for 50-kV voltage, 0.8-ns rise time, and 10-ns width. The switch and resistors are arranged in atmospheric air and the transmission line can work in atmospheric air or in transformer oil to change the pulse width from 6.7 ns to 10 ns. The fast switching and low-inductance characteristics of the polymer-film switch ensure the fast rising wavefront of <1 ns. This generator can be applied in the calibration of nanosecond voltage dividers and used for electromagnetic pulse tests as a fast-rising current injection source.

摘要

在本文中，我们描述了一种矩形脉冲发生器，它由一个聚合物薄膜开关、一个三板传输线和并联柱状陶瓷电阻负载组成，可产生50 kV电压、0.8 ns上升时间和10 ns脉宽的脉冲。开关和电阻布置在大气中，传输线可在大气中或变压器油中工作，以使脉冲宽度从6.7 ns变为10 ns。聚合物薄膜开关的快速开关和低电感特性确保了<1 ns的快速上升波前。该发生器可应用于纳秒分压器的校准，并作为快速上升电流注入源用于电磁脉冲测试。
