Abstract

본 발명은 개인용 컴퓨터에 접속된 모니터에 전원을 용이하게 공급하도록 하기에 적합한 개인용 컴퓨터의 전원 공급 장치에 관한 것으로, 종래의 기술에 있어서는 최초에 인가되는 상용 교류 전원을 개인용 컴퓨터에 접속된 모니터에서 인가 받아 사용할 때 현재 인가되는 상용 교류 전원의 전압 레벨이 그 모니터의 정격 전압과 다를 경우 이를 위해 별도의 변압 장비를 사용하거나 그 현재 인가되는 상용 교류 전원의 전압 케벨에 의해 구동할 수 있는 모니터로 교체해야 하는 등의 비경제적인 문제가 있었으나, 본 발명에서는 상용 교류 전원의 전압 레벨의 변화에 상관없이 모니터용 전원을 일정하게 유지시키므로 정격 전압이 AC 110v인 모니터를 상용 교류 전원 AC 220v에서도 이상없이 동작시킬 수 있는 것이다.The present invention relates to a power supply of a personal computer suitable for easily supplying power to a monitor connected to a personal computer. In the prior art, a commercial AC power initially applied in a monitor connected to a personal computer is applied. If the voltage level of the commercial AC power supply currently applied when used is different from the rated voltage of the monitor, a separate transformer or a monitor that can be driven by the voltage level of the commercial AC power supply currently applied should be replaced. Although there is an uneconomical problem, such as, in the present invention, the monitor power is kept constant regardless of the change in the voltage level of the commercial AC power, so that the monitor having the rated voltage of AC 110v can be operated without abnormality even in the commercial AC power AC 220v. It is.
