전류 THD 개선을 위한 가변 샘플링 시간이 적용된 3상 2-Level 인버터의 모델예측제어

This paper proposes a predictive current control method with variable sampling time. The proposed method improves the current THD based on the optimal voltage vector and its applied time. In this paper, the method to select the optimal voltage vector and the optimal sampling time period is proposed and it is compared with the conventional current THD reduction methods. The validity of the proposed method is verified through simulation.
