Abstract

본 발명은 스위칭 레귤레이터를 이용한 다출력 전원장치에서 직접 피드백 되지 않는 출력전압의 정전압 오차를 최소화 할 수 있도록 한 정전압 다출력 전원장치에 관한 것으로, 입력 교류전원을 정류기를 통해 DC전원으로 정류하여 트랜스의 일차권선에 제공하고, 다출력 전압증의 하나의 출력을 피드백 시켜 설정된 기준전압과 비교한 다음 이 비교결과에 의거하여 일차권선의 일측에 접속된 스위치를 온/오프 제어함으로서 트랜스의 다출력 전압을 일정하게 제어하는 다출력 전원장치에 있어서, 트랜스의 다출력 전압증 피드백 되지 않는 출력의 트랜스의 접지 접속핀이 피드백되는 출력전압에 접속되도록 구성함으로서, 직접 피드백 되지 않는 출력전압의 오차를 최소화하고 이차권선의 수를 줄여 제조공정을 용이하게 개선한 것이다.The present invention relates to a constant voltage multi-output power supply to minimize the constant voltage error of the output voltage that is not directly fed back from the multi-output power supply using a switching regulator, rectifying the input AC power to the DC power through the rectifier Provides to the primary winding, feeds one output of the multi-output voltage increase, compares it with the set reference voltage, and based on this comparison result, the multi-output voltage of the transformer is controlled by turning on / off the switch connected to one side of the primary winding. In the multi-output power supply which is controlled uniformly, the ground connection pin of the transformer of the output which is not fed back to the multi-output voltage of the transformer is configured to be connected to the output voltage to be fed back, thereby minimizing the error of the output voltage which is not fed back and the secondary By reducing the number of windings, the manufacturing process is easily improved.
