본문

본 논문에서는 개선된 적분기를 이용하여 3상 AC/DC 컨버터의 직접 전력 제어(Direct Power Control)를 위한 가상 자속의 추정

기법을 제안한다. 기존의 가상 자속 추정을 위해 사용하는 일반적인 적분기는 dc drift 문제를 유발한다. 이는 보통 저역 통과

필터를 사용으로 보완이 가능하지만, 이 경우 추정된 자속은 크기와 위상의 오차를 갖는다. 따라서 제안하는 기법은 각속도

오차가 가상 자속의 위상 지연 오차와 비례하는 관계를 분석하고 이를 보상하여 속응성 및 안정성을 향상시킨다. 시뮬레이션을

통하여 제안한 기법의 타당성을 검증한다
