基于直流母线电压解耦的整流电流调节的无电解电容永磁同步电机驱动谐波抑制

Harmonics suppression for grid currents is a key issue in electrolytic capacitorless permanent magnet synchronous motor drives. In this article, a strategy based on rectified current regulation with dc-link voltage decoupling (RCR-DVD) is proposed to enhance the harmonics suppression performance of grid currents. The small-signal model of the drive with RCR is built to reveal the disturbance cause...
