본 논문은 플로팅 커패시터를 갖는 듀얼 인버터의 스위치 손실 저감을 위한 전압 제어 기법을 제안한다. 플로팅 커패시터로 구성된 듀얼 인버터는 하나의 인버터의 직류단이 전원과 분리되어 있기 때문에 모터 제어뿐만 아니라 직류단의 전압 제어가 요구된다. 따라서 전원과 연결된 인버터는 유효전력을, 플로팅 커패시터와 연결되어 있는 다른 인버터는 무효전력을 출력한다. 각 인버터에서 출력하는 유효전력과 무효전력의 크기는 모터의 회전 속도 및 부하 토크의 크기에 따라 결정된다. 이때, 플로팅 커패시터와 연결된 인버터의 직류단 전압을 전압 변조지수(Modulation Index, MI)에 따라 조정할 수 있으며 직류단 전압의 크기에 따라 발생되는 스위칭 손실을 저감할 수 있다. 제안하는 플로팅 커패시터를 갖는 듀얼인버터의 스위치 손실 저감을 위한 전압 제어 기법의 타당성은 시뮬레이션을 통해 검증한다.
