The present invention relates to a power supply device for improving no-load power efficiency, which operates under no-load conditions. Provided is the power supply device comprising a flyback converter; a PWM control section for controlling the flyback converter through a switch operation; and a power supply control section for cutting off the power supply of the PWM control section to periodically generate an output voltage of a burst form in the no-load conditions. Therefore, the present invention has the effect of reducing power consumption by removing the power consumed in the no-load conditions. |
