A 250 kV, 1 MHz repetition rate square triple-pulses generator

This paper summarizes a novel method for high-power high repetition rate square pulse generator. By using high voltage rectifier diodes, three single square pulses are combined to form an MHz level repetition rate square tripl-pulse. Suitable connection design in parallel and in series lets the rectifier diodes stand high reverse voltage in high frequency and elevates rectified pulse current to kA level. The square triple-pulses generator has an output voltage up to 250 kV, a pulsed current of 10 kA, pulse power of 2.5 GW, a repetition rate of 1 MHz, a pulse risetime of 40 ns, and a pulse flat top of 50 ns.
