Abstract
In the present invention, when a DC reactor is in a magnetically saturated state, the on/off operations of a switching element are suspended and the switching element is set to an off state for a predetermined period of time, thereby resetting the magnetic saturation of the DC reactor and maintaining the supply of power to a load. After resetting the magnetic saturation, the pulse output of the normal pulse mode is restarted.
