1. A power supply device comprising:
a first switch element configured to selectively provide an alternating current (AC) power source to an actuation device;
a second switch element configured to selectively provide the AC power source to the first switch element;
a detection circuit configured to confirm whether the first switch element is in a full turn-on state by comparing an input power source and an output power source of the first switch element;
a sensor configured to sense a size of the AC power source; and
a controller configured to:
selectively control operation of the second switch element based on the sensed size of the AC power source and the confirmed full turn-on state of the first switch element.
