Static Switch Control of UPS with Active Filter Function
능동 필터 기능을 갖는 무정전전원장치의 정적 스위치 제어
Abstract
In this literature, when the utility line is normal, the Off-Line UPS operates as an active power filter to compensate the reactive power from a load, and when the utility line is in outage, the On-Line UPS opuates as in single phase inverter to supply an active and reactive power to the load. An additional static switch in UPS was used to decrease an transient state during these mode changes. And the result shows that the transient state disappeared.
