Pulse power supply device

A pulse power supply device comprising:

• a plurality of pulse power supplies each of which to output a pulse voltage that is monopolar;
• and
• a plurality of transformers each comprising a primary winding, a secondary winding, and a tertiary winding, wherein one of the pulse power supplies is connected to one of the primary windings on a one-to-one basis, wherein
• a plurality of the secondary windings are sequentially connected in series, both ends of a plurality of the secondary windings connected in series constitute output terminals, and a load is connected to the output terminals to form a first closed circuit,
• a plurality of the tertiary windings are sequentially connected in series, both ends of a plurality of the tertiary windings connected in series constitute voltage application terminals, a magnetic reset circuit is connected to the voltage application terminals, and a plurality of the tertiary windings and the magnetic reset circuit form a second closed circuit, and
• the magnetic reset circuit comprises:
• a magnetic reset power supply that is a power supply to cause a reset current to flow through the tertiary windings;
• and
• an impedance changing circuit configured to be able to change an impedance for limiting an induced current that is possible to be caused to flow in the second closed circuit by a voltage induced in the tertiary windings.
