Development and experimental research on the fast rise time EMP generator

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 3ns, with the pulse width around 58ns and amplitude up to 4kV. It can also generate square wave with rise time less than 2ns and amplitude up to 4kV. 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.
