Abstract

Pulse generators with high voltage and several nanoseconds of rise time are typically used to carry out the equivalent assessment of the protection performance of typical power equipment in the high-altitude electromagnetic pulse environment. In this paper, a pulse generator with high voltage and fast rise time has been designed, and the diagnostic system with high temporal resolution has been integrated to measure the output pulse voltage of the generator. The experimental results showed that the output pulse voltage of the generator on the output load can reach 645 kV when the charged voltage of Marx generator capacitors is 40 kV. The rise time of the generator is 8.2-9.9 ns when the charged voltage of Marx generator capacitors is in the range of 20-40 kV.

700 千伏脉冲发生器，上升时间约为几纳秒。

高电压和几纳秒上升时间的脉冲发生器通常用于在高空电磁脉冲环境下对典型电力设备的保护性能进行等效评估。本文设计了一种具有高电压和快速上升时间的脉冲发生器，并集成了具有高时间分辨率的诊断系统来测量发生器的输出脉冲电压。实验结果表明，当 Marx 发电机电容器的带电电压为 40 kV 时，发电机在输出负载上的输出脉冲电压可达 645 kV。当 Marx 发生器电容器的充电电压在 20-40 kV 范围内时，发生器的上升时间为 8.2-9.9 ns。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
