Abstract
이 발명은 트랜스와 이 트랜스의 일측에 연결되어 트랜스의 입력전압 듀디비를 제어하는 SMPS를 구비한 전원공급회로에 있어서, 트랜스에서 유기된 출력전압을 검출하여 기준전압과 비교한 후 과전압이 발생했을때만 포토커플러를 도통시켜 SMPS에 입력되는 전압 듀티비를 제어하는 것을 특징으로 한다.The present invention provides a power supply circuit having a transformer and an SMPS connected to one side of the transformer to control the input voltage duty ratio of the transformer, wherein an output voltage generated by the transformer is detected and compared with a reference voltage to generate an overvoltage. Only when the photocoupler is turned on to control the voltage duty ratio input to the SMPS.
