Abstract
A second DC power-supply voltage that is obtained by outputting a first DC power-supply voltage obtained by converting an AC power supply into a direct current in an AC-DC converter circuit, through a first switch for PWM switching is smoothed and fed to a load as an output DC power-supply voltage. The first DC power-supply voltage is also supplied to a battery through a third switch for PWM switching and the battery is thereby charged. Further, a third power-supply voltage output from the battery is output to the output side of the first switch through a fourth switch for PWM switching.
