Abstract
This DC pulse power supply device includes: a DC power supply unit (); and a pulsing unit () that generates a pulse output using a step-up chopper circuit connected to the DC power supply unit. A clamp voltage unit () has an output end that is connected to a connection point (s) between a switching element () and a DC reactor (), and applies a clamp voltage (VC) to one end of the switching element (). During an off period (Toff) of the step-up chopper circuit, the voltage at both ends of the switching element is clamped so as to prevent damage to the switching element, suppress output voltage fluctuations resulting from load current fluctuations, and suppress power loss caused by a load current and a discharge current flowing through a resistor.
