UPS 기능을 갖는 내장형 컴퓨터 전원장치의 구현
Implementation of inside the computer power supply with UPS
초록
Recently, UPS(Uninterruptible Power Supply) have been largely used to improve power souse quality as well as to protect critical loads such as computer, industrial system, medical equipment, etc, against power outage by providing clean and uninterrupted power under power supply disturbance or interruptions. But UPS is bulky because used battery. So, UPS size issue have received attention in the power electronics industry. Therefore, this paper proposed a implementation of inside of the computer power supply with UPS by the one-chip microprocessor to minimize UPS size. To verify the proposed power supply, the detail simulation and experiment results indicate that high-frequency switching and operation UPS can be achieved.
