概述本文介绍了减少由电流源逆变器供电的态应电动机传动系统中通常出现的转矩脉动的三种反鐀补尝方案。该方法不仅经过了精细的计算机模拟,而且还由实际系统的试验结果所证实。还讨论了■差频率接近于零时(无载),该方法的局限性,并推荐了清除这一问题的方法。 Overview This article describes three strategies to reduce the torque ripple that usually occurs in the drive system of a motor drive system that is powered by a current source inverter. This method has not only been subjected to detailed computer simulations, but also confirmed by experimental results of actual systems. It also discusses the limitations of the method when the difference frequency is close to zero (no load), and recommends ways to clear this problem.
