Abstract

The proposed dobule phase locked loop and active multiple interphase reactor are used to eliminate the circular current and the voltage ripples caused by the system parameter unbalance of parallel connected UPSs. In this paper, digital controller for the dobule PLL and active interphase reactor is implemented with ADSP21061 as an aspect of functional convenience.

병렬로 구성되 UPS 사이에 파라미터 불일치에 따른 순환전류와 전압리플이 발생되어지는데, 이들은 전체 UPS 시스템의 고장 및 신뢰성 저하를 유발한다. 본 논문에서는 이러한 문제점들은 Double 위상동동기기와 능동 다중인 터페이스 리액터를 사용하여 해결하였다. 또한 ADSP21061을 사용하여 제어기를 디지털적으로 구현하였다.
