一种用于无电解电容IPMSM驱动系统的高功率因数转矩脉动抑制新方法

The torque ripple is an important concern in the electrolytic capacitor-less interior permanent magnet synchronous motor (IPMSM) drive system. In this article, a novel method based on d-axis harmonic current injection is proposed to reduce the torque ripple while maintaining a high power factor. The main fluctuating components in the torque with respect to the d-q axis current are derived, and pos...
