摘要
针对国际电工委员会1996年制定的IEC61000 2 9和美国国防部1999年修定的MIL STD 461E标准提出的高空核爆电磁脉冲波形,研制了一台新型纳秒高压脉冲源。其产生的双指数波脉冲前沿小于3ns,脉宽58ns,幅度可达4kV,此外还可产生前沿小于2ns、幅度最高为4kV的脉冲方波;两种脉冲均可实现单次和间歇可调输出。介绍了脉冲源的电路设计和调试结果,通过实验对比了MIL STD 461E与MIL STD 461D两种双指数波形条件下某测控系统模块的干扰耦合效应。
A novel high voltage pulse generator is developed for the simulation of HEMP according to the standard of IEC61000-2-9 and MIL-STD-461E. The generator can produce both single and repeated pulse. Its double-exponential output has a rise time less than 3 ns, with the pulse width around 58 ns and amplitude up to 4 kV. It can also generate square wave with rise time less than 2 ns and amplitude up to 4 kV. The circuit design and experimental test of the pulse generator are introduced in this paper. The test result is also presented to show the difference of the interference effect produced by the new generator and the original HEMP defined in MIL-STD-461D.
