Abstract
1. 청구범위에 기재된 발명이 속하는 기술분야1. TECHNICAL FIELD OF THE INVENTION
본 발명은 로직(logic) 회로를 구비한 시스템에서 로직회로에 인가되는 전원을 제어하기 위한 전원 제어장치에 관한 것이다.The present invention relates to a power supply control device for controlling a power applied to a logic circuit in a system having a logic circuit.
2. 발명이 해결하고자 하는 기술적 과제2. Technical problem to be solved by the invention
본 발명의 목적은 정전압 전원회로의 장애로 인하여 로직회로에 과전압이 인가될 경우 로직회로를 보호하기 위한 전원 제어장치를 제공함에 있다.An object of the present invention is to provide a power supply control device for protecting a logic circuit when an overvoltage is applied to the logic circuit due to a failure of the constant voltage power circuit.
3. 발명의 해결방법의 요지3. Summary of Solution to Invention
교류상용전원을 정류하여 발생한 직류전원의 전압을 강하시켜 정전압의 시스템 구동전원을 발생하고, 상기 시스템 구동전원의 전압을 강하시켜 로직회로를 동작시키기 위한 정전압의 로직전원을 발생한다. 이 때 상기 로직전원의 전압을 상기 직류전원의 전압과 비교하여 상기 로직전원의 과전압 상태가 검출될 경우 상기 시스템 구동전압을 설정 레벨 이하로 강하시킨다.A voltage of a DC power source generated by rectifying an AC commercial power source is dropped to generate a system driving power source having a constant voltage, and a voltage of the system driving power source is dropped to generate a constant-voltage logic power source for operating a logic circuit. At this time, when the voltage of the logic power supply is compared with the voltage of the DC power supply, when the overvoltage state of the logic power supply is detected, the system driving voltage is lowered below the set level.
4. 발명의 중요한 용도4. Important uses of the invention
본 발명은 로직회로를 채용한 시스템에 이용된다.The present invention is used in a system employing a logic circuit.
