Abstract

본 발명은 전원 공급 장치에 관한 것으로서, 특히 제어부를 구동시키기 위하여 검출되는 전원 공급 장치의 출력 전압을 가변시킴으로써, 제어부에 인가되는 전압을 일정하게 유지시키는 전원 공급 장치의 출력 전압 가변 회로에 관한 것이다. 이와 같은 본 발명은 부하에 인가되는 출력 전압을 검출하는 출력 전압 검출부와, 출력 전압 검출부에서 출력되는 신호에 의해 스위칭부의 스위칭 시간을 제어하는 제어부로 구성되는 전원 공급 장치에 있어서, 상기 출력 전압 검출부가 부하에 인가되는 출력 전압이 분배되어 출력 전압이 설정된 전압이하로 출력 전압 검출기에 인가되는 분배 수단이 더 포함된다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply, and more particularly, to an output voltage varying circuit of a power supply for maintaining a constant voltage applied to a control by varying an output voltage of a power supply detected to drive a control. As described above, the present invention provides a power supply comprising an output voltage detector for detecting an output voltage applied to a load, and a controller for controlling a switching time of the switching unit by a signal output from the output voltage detector. Distribution means for distributing the output voltage applied to the load is applied to the output voltage detector less than the set voltage.
