Abstract

본 발명은 전자기기의 전원제어회로에 관한 것으로서, 특히 각종 전기 전자기기 또는 내부 부품의 단락(SHORT)시 전자기기에 공급되는 주전원을 차단하여 과부하로 인한 전자부품의 파손을 방지할 수 있도록 하는 전자기기의 전원제어회로에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply control circuit of an electronic device. In particular, the present invention relates to an electronic device capable of preventing damage to an electronic component due to an overload by cutting off main power supplied to an electronic device during a short circuit of various electronic devices or internal parts. The present invention relates to a power supply control circuit of a device.

이를 위하여 AC전원이 인가되는 전원부에 의해 동작하는 부하의 단락시 상기 전원부로 공급되는 것을 차단시켜 과전압으로 부터 부하를 보호하는 전자기기의 전원제어회로에 있어서, 상기 부하의 일측에 연결되어 정상적인 상태일 경우 충전이 이루어지고, 단락시 방전을 실행하는 충방전부, 상기 충방전부의 출력신호 레벨에 따라 온·오프상태로 제어되는 제1스위칭부, 상기 제1스위칭부의 일측과 전원부 입력단 사이에 접속되어 AC전원을 분압하는 전압분배부, 상기 제1스위칭부 및 전압분배부의 일측과 병렬접속되고 전원부의 입력단 사이에 연결되어, 부하 단락시 전원부에 공급되는 전원을 차단시키는 제9스위칭부를 구비하여서 된 것이다.To this end, in a power control circuit of an electronic device that protects a load from overvoltage by blocking supply to the power supply when a load operated by a power supply unit to which AC power is applied, the power control circuit of the electronic device is connected to one side of the load in a normal state. In this case, the charging is performed, the charging and discharging unit which discharges at the time of short-circuit, the first switching unit to be controlled on and off according to the output signal level of the charging and discharging unit, connected between one side of the first switching unit and the power input terminal The voltage divider for dividing the power, the first switching unit and the ninth switching unit is connected in parallel with one side of the voltage distribution unit and connected between the input terminal of the power supply unit to cut off the power supplied to the power supply unit in the event of a load short circuit.
