Abstract
본 발명은 부하변동이 많은 복합영상기기에 있어서, 부하변동이 있을때마다 이를 감지하여 자동으로 입력전압비를 제어해 주는 스위칭 전원의 회로에 관한 것이다.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 composite video apparatus having a large load variation.
본 발명에 의하면 부하변동이 생길때 마다 이를 릴레이 및 트랜지스터가 감지하여 미리 설정된 전압과 비교하여 그 차이값을 스위칭 모드 전원 공급회로에 알리기 때문에 입력전압의 세기를 조절 할 수 있다.According to the present invention, whenever the load fluctuation occurs, the relay and the transistor detects it and compares it with a preset voltage and informs the switching mode power supply circuit of the input voltage, thereby adjusting the strength of the input voltage.
따라서, 방송모드변동에 따라 발행하는 변동에 따라 전압변동을 신속히 제어할 수 있는 것이다.Therefore, it is possible to quickly control the voltage fluctuation according to the fluctuation issued by the broadcast mode fluctuation.
