Abstract

본 발명은 모터구동 인버터의 데드타임 보상에 관한 것으로, 종래의 방법은 단순히 전류의 극성이 바뀌는 것만 고려함으로 인해 즉, 전류의 극성을 판달할때 양과 음의 오프셋을 사용하기 때문에 데드타임 보상전압이 음에서 양으로 또는 양에서 음으로 바뀌는 순간에 발생하는 실제 전류파형의 왜곡으로 인하여 토오크리플이 발생하며, 이러한 전류파형의 왜곡은 저속일수록 토오크리플의 발생을 크게하는 문제점이 있다.
본 발명은 기존의 보상장치에 추가로 전류의 극성이 변화할 시점을 계산하여 이로부터 히스테리시스 밴드사이에서 전류지령을 산출하고 이 전류지령으로 부터 새로운 전압지령을 인버터에 하달함으로써 종래 데드타임 보상에도 불구하고 발생하는 전류의 왜곡을 최소한으로 줄일 수 있게되어 토오크리플, 특히 저속운전시 발생하는 토오크리플을 감소시키는 효과가 있다.
