Abstract

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 possible configurations of the d-axis current reference are analyzed to obtain an optimal solution to reduce the torque fluctuations. To further improve the power factor, an active damping method based on virtual damping resistor is used to suppress harmonics in the grid current, and a feedforward power compensation link is added to improve the grid current quality. The torque ripple component can be reduced and the requirements of EN61000-3-2 can be satisfied by applying the proposed method. Experimental results on an IPMSM drive platform with a small film capacitor verify the effectiveness of the proposed method.

用于无电解电容器 IPMSM 驱动系统的具有高功率因数的新型扭矩纹波抑制方法

转矩脉动是无电解电容内插式永磁同步电机驱动系统中的一个重要问题。本文提出了一种基于d轴谐波电流注入的新方法，在保持高功率因数的同时减小转矩脉动。推导了转矩与d-q轴电流相关的主要波动分量，分析了d轴电流基准的可能配置，得到了减小转矩波动的最优解。为了进一步提高功率因数，采用基于虚拟阻尼电阻的有源阻尼方法抑制电网电流中的谐波，并增加前馈功率补偿环节改善电网电流质量。采用该方法可以减小转矩脉动分量，满足EN61000-3-2的要求。在一个小型薄膜电容的永磁同步电动机驱动平台上的实验结果验证了该方法的有效性。

期刊介绍： The IEEE Transactions on Power Electronics journal covers all issues of widespread or generic interest to engineers who work in the field of power electronics. The Journal editors will enforce standards and a review policy equivalent to the IEEE Transactions, and only papers of high technical quality will be accepted. Papers which treat new and novel device, circuit or system issues which are of generic interest to power electronics engineers are published. Papers which are not within the scope of this Journal will be forwarded to the appropriate IEEE Journal or Transactions editors. Examples of papers which would be more appropriately published in other Journals or Transactions include: 1) Papers describing semiconductor or electron device physics. These papers would be more appropriate for the IEEE Transactions on Electron Devices. 2) Papers describing applications in specific areas: e.g., industry, instrumentation, utility power systems, aerospace, industrial electronics, etc. These papers would be more appropriate for the Transactions of the Society which is concerned with these applications. 3) Papers describing magnetic materials and magnetic device physics. These papers would be more appropriate for the IEEE Transactions on Magnetics. 4) Papers on machine theory. These papers would be more appropriate for the IEEE Transactions on Power Systems. While original papers of significant technical content will comprise the major portion of the Journal, tutorial papers and papers of historical value are also reviewed for publication.
