Abstract

In a voltage-type DC power supply provided with an inverter, current supply from the inverter to the load side is suppressed when arc is generated. DC output from the voltage-type DC power supply is suspended and resumed: upon suspending the DC output, the chopper is separated from the inverter, thereby suppressing excessive current to the load when arc is generated, allowing the arc to be extinguished at high speed, and holding the current passing through the chopper in the form of circulating current. Upon restarting the inverter, the circulating current being held is supplied to the load, thereby reducing a delay of supply of DC power to the load at the time of resuming the DC output from the voltage-type DC power supply.
