Abstract
본 발명은 부하변동에 많은 복합영상기기에 있어서, 부하변동이 있을 때마다 이를 감지하여 자동으로 입력 전압비를 제어해주는 스위칭 전원의 회로에 관한 것이다. 본 발명에 의하면 부하변동이 생길때마다 이를 릴레이 및 트랜지스터가 감지하여 미리 설정된 전압과 비교하여 그 차이값을 스위칭 모드 전원공급회로에 알리기 때문에 입려 전압의 세기를 조절할 수 있다. 따라서 방송모드 변동에 따라 발생하는 부하변동에 따른 전압변동을 신속히 제어할 수 있는 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circuit of a switching power supply that detects a load variation and automatically controls an input voltage ratio in a complex video device having a lot of load variation. According to the present invention, whenever the load fluctuation occurs, the relay and the transistor sense and compare with the preset voltage and inform the switching mode power supply circuit so that the intensity of the applied voltage can be adjusted. Therefore, it is possible to quickly control the voltage fluctuations caused by the load fluctuations caused by the broadcast mode fluctuations.
