본문

본 논문은 계통연계형 3-레벨 NPC 인버터 시스템의 중성점 전압 불평형 제어기법을 제안한다. 3-레벨 NPC 인버터는 직류단 커패시터를

2개로 나누어 사용하기 때문에 두 커패시터간의 전압차이가 발생할 수 있으며 이는 출력전류의 왜곡을 야기한다. 본 논문에서는 복잡한

모델링을 통한 제어기 설계나 공간 벡터 전압 변조 방법의 변형 없이 간단하게 시간오프셋을 추가하여 N형과 P형의 small 전압 벡터의

인가시간을 조절함으로써 중성점 전압 불평형을 제어하고, 복잡한 계산 없이 적절한 시간오프셋을 구한다. 10kW급 계통연계 3-레벨

NPC 인버터 모델을 기반으로 수행된 시뮬레이션 결과를 바탕으로 제안하는 제어기법의 타당성을 보인다.
