Through studying the mechanism of the electric exploding, an inductive storage circuit with two electric explosive switches is designed to produce shot nanosecond pulse by chopped wave.

Then, transform it through the pulse sharpening circuit consisting mainly of capacitances and magnetic switches, finally outputting the high voltage and high repetition rate nanosecond pulses.

Based on the avalanche effect, a kind of kilo-volt nanosecond pulsers has been designed, by using microwave PCB (printed circuit board).
