Abstract
A power supply device is provided. The power supply device includes a first switch element for selectively providing an alternating current (AC) power source to an actuation device, a second switch element for selectively providing the AC power source to the first switch element, a detection circuit for confirming whether or not 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 for sensing the size of the AC power source, and a controller for selectively controlling the operation of the second switch element on the basis of the sensed size of the AC power source and the confirmed full turn-on state.
