Classification: CPC H | IPC H

Claim 0:
1. 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.
