Abstract

A pulsed power supply apparatus includes a plurality of first inductors arranged in a first column in series connection; a plurality of second inductors arranged in a second column in series connection; a plurality of capacitors; a plurality of negative-side switching elements; a plurality of positive-side switching elements; a first positive terminal switching element connected to a first inductor of the plurality of first inductors that is located at one end of the plurality of first inductors and to a first output terminal; and a first negative terminal switching element connected to a second inductor of the plurality of second inductors that is located at one end of the plurality of second inductors and to the first output terminal.

Claims (17)

1 . A pulsed power supply apparatus comprising:

a plurality of first inductors arranged in a first column in series connection;

a plurality of second inductors arranged in a second column in series connection;

a plurality of capacitors;

a plurality of negative-side switching elements;

a plurality of positive-side switching elements;

a first positive terminal switching element connected to a first inductor of the plurality of first inductors that is located at one end of the plurality of first inductors and to a first output terminal;

a first negative terminal switching element connected to a second inductor of the plurality of second inductors that is located at one end of the plurality of second inductors and to the first output terminal;

a second positive terminal switching element connected to a first inductor of the plurality of first inductors that is located at an opposite end of the plurality of first inductors and to a second output terminal;

a second negative terminal switching element connected to a second inductor of the plurality of second inductors that is located at an opposite end of the plurality of second inductors and to the second output terminal; and

a direct-current power supply connected to the second positive terminal switching element and the second negative terminal switching element, wherein

an i-th capacitor of the plurality of capacitors is connected to a second end of a first inductor of the plurality of first inductors that is located in an i-th row of the first column and to a second end of a second inductor of the plurality of second inductors that is located in the i-th row of the second column,

i is an integer greater than or equal to 1,

an i-th negative-side switching element of the plurality of negative-side switching elements is connected to the second end of the first inductor of the plurality of first inductors that is located in the i-th row of the first column and to a first end of the second inductor of the plurality of second inductors that is located in the i-th row of the second column, and

an i-th positive-side switching element of the plurality of positive-side switching elements is connected to a first end of the first inductor of the plurality of first inductors that is located in the i-th row of the first column and to the second end of the second inductor of the plurality of second inductors that is located in the i-th row of the second column.

2 . The pulsed power supply apparatus according to claim 1 , wherein

each of the plurality of second inductors is a saturable inductor.
