摘要
逆变器非线性、反电动势波形非正弦等因素会使得永磁同步电机绕组电流中包含5、7次谐波,从而导致电机转矩波动,并使电机产生振动和噪声,影响系统的控制性能。本文对电流谐波抑制策略进行综述,阐述其原理,并进行实验对比。
There are 5th and 7th current harmonics in permanent magnet synchronous motor (PMSM) due to nonlinearity of the inverter and nonsinusoidal back electromotive forces, which produces torque ripple, vibration and noise, and affects performance of the system. In this paper, the current harmonics suppression strategies are reviewed, and their principles are introduced. And also, experimental results and comparisons are shown to compare these methods.
