Abstract
본 발명은 전원 자동 전환 회로로서 외부 전원부로부터 인가되는 입력 교류전압을 감지하여 자동으로 해당구동전압으로 전환시켜 주는 입력전원 자동전환회로에 관한 것 외부전원부로부터 인가된 전압을 감지하여 인가된 전압이 저전압(90V~180V)이면 자동으로 일정고전압(250V)으로 승압시켜 전원공급부에 인가하고, 인가된 전압이 고전압(180V~265V)이면 자동으로 이를 감지하여 승압시키지 않고 직접 전원공급부에 인가하게 된다.The present invention relates to an automatic power supply switching circuit for detecting an input AC voltage applied from an external power supply unit and automatically converting the input AC voltage into a corresponding driving voltage. If it is (90V ~ 180V) it is automatically boosted to a constant high voltage (250V) and applied to the power supply, and if the applied voltage is a high voltage (180V ~ 265V) it is automatically detected and applied directly to the power supply without boosting.
따라서 외부 전원부로부터 입력되는 전압량에 관계없이 전자기기를 사용하게 되므로 사용이 편리하고, 별도의 수동 동작이 필요치 않아 기기의 파손등의 사고가 발생치 않게 된다.Therefore, since the electronic device is used regardless of the amount of voltage input from the external power supply, it is convenient to use, and no manual operation is required so that an accident such as damage to the device does not occur.
