무정전전원 기능을 갖는 라인인터액티브형 3상 능동전력필터 = Line-interactive 3-Phase Active Power Filter with Function of Uninterruptible Power Supply

다국어 초록 (Multilingual Abstract)

This paper describes a line-interactive 3-phase active power filter with function of uninterruptible power supply. Presented control algorithm makes one converter perform two functions according to source conditions. One is APF function for harmonic current suppression caused by nonlinear loads in normal power condition and the other is for UPS when the power condition is abnormal<br/>
These two changeable operation modes explain the feasibility of improving system efficiency, compared with that of UPS system which has low utilization efficiency. Hence this paper suggests the way of changing operation by a source con야tion detecting algorithm.
