본문

본 논문은 멀티레벨 인버터를 이용한 무정전 전원장치 시스템 (UPS; Uninterruptible Power Supply)의 신뢰성 향상을 위한 중성점

전압 불평형 제어 기법을 제안한다. 무정전 전원장치 시스템 (UPS)은 불평형 부하조건 시 직류단에 전압 불평형이 발생되며 이는

출력 전류의 왜곡을 일으켜, 민감한 부하에 손상을 입힐 수 있다. 제안한 제어기는 커패시터 전압 측정을 통해 시간오프셋을

추정한 후 공간 벡터 변조 방식의 변형 없이 중성점 전압 불평형을 제어하여, 직류단의 전압을 평형상태로 유지한다. 또한,

100kW급 UPS 시스템 시뮬레이션 검증을 통해 제어기의 타당성을 입증하였다.
