Abstract
An exemplary embodiment of the present invention relates to a power supply. A power supply according to an exemplary embodiment of the present invention includes: a filter capacitor coupled to a line to which an input voltage rectified from an AC input passed through a dimmer is supplied; a discharge switch coupled to the filter capacitor through the line; and a main switch receiving the input voltage and controlling power transmission. The power supply performs input voltage control to shape the input voltage with a predetermined pattern and controls a switching operation time of the main switch.
