    • A high-voltage pulse generating circuit has an inductor, a first semiconductor switch, and a second semiconductor switch which are connected in series between opposite terminals of a DC power supply unit, and a diode having a cathode terminal connected to a terminal of the inductor which has another terminal connected to an anode terminal of the first semiconductor switch, and an anode terminal connected to a gate terminal of the first semiconductor switch.
