Abstract

본 발명은 가전기기 등의 에스엠피에스 전원 장치와 관련된 것으로서, 종래에는 이러한 전원장치에서 시스템 파워가 오프된 상태에서도 스위칭 구동부의 동작이 계속되도록 설계되어져 있기 때문에 이러한 전원부위에서의 불요 전력 낭비를 피하기 어려운 것이었다.The present invention relates to an SMP power supply device such as a home appliance, and in the related art, it is difficult to avoid unnecessary power waste in such a power supply area because it is designed to continue the operation of the switching driver even when the system power is turned off. .

본 발명은 이러한 문제점을 개선할 수 있도록 상기 시스템의 스위칭 구동부(24)와, 스위칭 트랜스(23)의 출력측과, 전원출력부(28) 및 부하기기의 입력측에 제각기 연결되어져서 시스템 전원이 오프되었을 시에는 부하기기 입력측에 밧데리(14) 전원을 제공하고, 한편으로는 스위칭 구동부(24)를 오프시키도록 동작하는 절전제어 회로(1)가 구비되어져 있는 구성을 특징으로 하는 가전기기 등의 절전형 스위칭 모드 전원회로를 제공하는데 있다.The present invention is connected to the switching drive unit 24, the output side of the switching transformer 23, the power output unit 28 and the input side of the load device of the system so that the system power is turned off so that this problem can be improved. Power-supply switching, such as a home appliance, characterized in that the battery 14 is supplied to the load device input side, and on the other hand, a power saving control circuit 1 is operable to turn off the switching driver 24. It is to provide a mode power circuit.
