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.
具有高电压和几纳秒上升时间的脉冲发生器通常用于对高海拔电磁脉冲环境下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，当马克思发生器电容器的充电电压为40 kV时，发生器在输出负载上的输出脉冲电压可达645 kV。当马克思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。
