Abstract
본 발명은 전원 공급 장치에 관한 것으로서, 특히 입력되는 고전압으로 인해 레귤레이터가 파괴되는 것을 방지함으로써, 모니터의 신뢰성을 향상시길 수 있는 전원 공급 장치의 레귤레이터 보호 회로에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply, and more particularly, to a regulator protection circuit of a power supply that can improve the reliability of a monitor by preventing the regulator from being destroyed by a high voltage input.
이와같은 본 발명은 제1전원부가 트랜스포머의 여자된 전압을 반파 정류시킨 후 평활되고 평활된 작은 전압이 상기 제1전원 제어부를 통해 제2전원부에 인가되는 다이오드(D11) 및 콘덴서(C11)과, 상기 다이오드(D11) 및 콘덴서(C11)의 출력 전압을 반파 정류시킨 후 평활되어 제1부하에 인가시키는 다이오드(D12) 및 콘덴서(C12)로 구성된다.The present invention is a diode (D11) and capacitor (C11) is applied to the second power supply unit through the first power control unit after the first power supply unit half-wave rectified the excitation voltage of the transformer by the first power control unit, The diode D11 and the capacitor C12 are rectified by half-wave rectification of the output voltages of the diode D11 and the capacitor C11 and applied to the first load.
