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.
