본문

본 논문은 개방 권선 구조의 매입형 영구자석 동기기(Open-End Winding Interior Permanent Magnet Synchronous Motor, OEW IPMSM)를 구동하는 듀얼 인버터의 스위칭 손실 저감을 위한 가변 불연속 변조(Discontinuous PWM, DPWM) 기법을 제안한다. OEW IPMSM은 다수의 전력 반도체를 갖는 듀얼 인버터로 구동되며, 손실에 의한 전력 반도체의 온도 변화는 인버터의 주된 고장요인 중 하나이다. 본 논문에서는 전속도 영역에서 최대 전류점을 계산하고 DPWM 기법을 사용하여 스위칭 손실을 저감한다. 제안하는 기법의 성능 및 타당성은 시뮬레이션 결과를 통해 검증한다.
