摘要
The stator current harmonics can be caused by the sampling mode and control delay of the DC-link voltage. The interaction between the stator current harmonics and the fundamental current stimulates the beat phenomenon, which causes additional noise and low frequency fluctuation. The voltage reconstruction strategy based on the DC-link voltage periodic characteristic is proposed, which effectively improves the drive system performance. By applying the plug-in repetitive controller, the DC-link voltage specific components in the prospective switching period can be predicted. The experimental results prove the effectiveness of the proposed method.
