Abstract

이 발명은 노트북 퍼스널 컴퓨터 전원 공급 장치의 전류 분배회로에 관한 것으로서, 정전류 AC/DC 어뎁터에 전류 분배기가 연결되고, 상기 전류 분배기의 제1출력단에 컴퓨터 시스템에 연결되고 전류 분배기의 제2출력단에 밧데리가 연결되어 구성되는 이 발명은 정전류 AC/DC 어뎁터를 이용해 일정 전류를 출력시키면 전류 분배기에서는 컴퓨터 시스템의 구동에 필요한 전류를 공급하고 나머지 전류를 밧데리에 공급해 밧데리를 충전시킨다. 따라서 밧데리를 사용하는 노트북 퍼스널 컴퓨터에서 밧데리를 컴퓨터 구동시 함께 충전하는데 적용된다.The present invention relates to a current distribution circuit of a notebook personal computer power supply, comprising: a current divider connected to a constant current AC / DC adapter; a first output end of the current divider connected to a computer system; and a battery at a second output end of the current divider. In the present invention, which is configured to be connected to a constant current using a constant current AC / DC adapter, the current divider supplies the current required for driving the computer system and supplies the remaining current to the battery to charge the battery. Therefore, in the notebook personal computer using the battery, it is applied to charge the battery when the computer is running.
