Abstract：Design a high-voltage pulse simulator through principle analysis， engineering calculation， and modeling to simulate interference tests of instantaneous high-voltage signals in electromagnetic environments. The high-voltage pulse simulator utilizes a high-voltage vacuum relay for polarity conversion and a high-voltage mercury switch for discharge. After testing， the high-voltage pulse simulator has achieved a ns level rising edge and a pulse width of 1 μs. High-voltage pulse output with a load of 50 Ω and an amplitude of 1.5 kV.
