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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power supply device","description":"An exemplary embodiment of the present invention relates to a power supply.
