본문

본 논문에서는 3-레벨 Neutral-Point-Clamped (NPC) 인버터의 DC-Link 중성점 전압 리플을 저감하여 인버터 출력 전압의 품질

신뢰성 향상이 가능한 새로운 Discontinuous Pulse Width Modulation (DPWM) 기법을 제안한다. NPC 인버터에서는 두 개의

커패시터로 이루어진 DC-Link 구조로 인해 상, 하단 DC-Link 커패시터 전압 불평형인 상황에서 DC-Link 중성점 전압 리플이

발생한다. 중성점 전압 리플 발생 시 출력 전압의 품질을 보장할 수 없으며, 민감한 부하에 손상을 입힐 수 있다. 제안한 DPWM

알고리즘은 DC-Link 커패시터 전압을 조정하는 두 개의 오프셋을 사용하여 중성점 전압 리플을 저감한다. 또한, 시뮬레이션을

통해 본 논문에서 제안한 알고리즘의 타당성을 검증한다.
