Abstract
This DC-pulse power supply device is provided with: a DC power supply; a pulse unit () for generating a pulse output using a step-up chopper circuit connected to the DC power supply; and a voltage superimposing unit (A,B) connected to a DC reactor of the step-up chopper circuit. The voltage superimposing unit (A,B) superimposes an amount (Vc, VDCL) corresponding to a superimposed voltage on the output voltage of the step-up chopper circuit. The pulse unit () outputs, in a pulse form, the output voltage (Vo) on which the amount (Vc, VDCL) corresponding to the superimposed voltage is superimposed by the voltage superimposing unit (A,B). The amount corresponding to the superimposed voltage is superimposed on the pulse output of the step-up chopper circuit, thereby raising the output voltage of the pulse output of the step-up chopper circuit.
