基于自适应虚拟导纳重塑的无小直流母线电容永磁同步电机驱动谐振抑制策略

Active damping strategies can suppress the LC resonance for electrolytic capacitorless permanent magnet synchronous motor (PMSM) drives, yet it is difficult for the fixed damping coefficient to achieve optimal performance under different operating states. In this article, a novel adaptive virtual admittance reshaping-based resonance suppression strategy is proposed. The influence regularity of the...
