Repetitive frequency impulse voltage generator based on magnetic switches

The novel repetitive frequency impulse voltage generator utilizes both the feature “high repetitive rate and magnetic compression” of magnetic switch and the feature “charging in parallel and discharging in series” of Marx generator. It is possible to generate high voltage impulses with rapid rise time and high repetition rate by replacing the spark gaps in the traditional impulse voltage generator with magnetic switches. A magnetic switch based impulse voltage generator was built and the output impulses with a magnitude of 17 kV, a rise time of 80 ns and a repetition rate of 1 kHz were achieved on a 1 nF capacitive load.
