The present invention relates to a power supply device. According to an embodiment of the present invention, the power supply device comprises: an AC/DC converting unit configured to convert input AC power into DC power; a DC/DC converting unit configured to convert the DC power into output power by using a primary side coil and a secondary side coil electrically insulated from the primary side coil; and a standby power generating unit configured to generate standby power by using the input AC power. Therefore, the power supply device can stably supply standby power while consuming a small amount of power in a standby mode. 본 발명은 전원 공급 장치에 관한 것으로서, 본 발명의 일 구현예에 따른 전원 공급 장치는 입력 교류 전원을 직류 전원으로 변환하는 교류 직류 변환부, 1차측 코일과, 상기 1차측 코일과 전기적으로 절연된 2차측 코일을 이용하여 상기 직류 전원을 출력 전원으로 변환하는 직류 직류 변환부 및 상기 입력 교류 전원을 이용하여 대기 전원을 생성하는 대기 전원 생성부를 포함할 수 있다.
