About this book

The book presents a focused study on electrolytic capacitorless permanent magnet synchronous motor (PMSM) drives and their associated control strategies. It addresses both theoretical foundations and engineering practices through a comprehensive exploration of key topics, including system modeling, analytical principles for engineering challenges, control method design, experimental validation, and performance evaluation.

Five critical engineering challenges are examined in depth:

Methods for improving power quality, Grid current enhancement strategies under non-ideal grid conditions, Suppression techniques for motor-side beat phenomena, Low-distortion overmodulation methods, Strategies for expanding the linear modulation region.

A distinctive feature of the book is its systematic and application-oriented treatment of practical issues in capacitorless PMSM drive systems. This makes it particularly valuable for readers seeking effective, real-world solutions.

The book is intended to benefit researchers, engineers, and graduate students in the fields of power electronics, electric drives, and control engineering.

Table of Contents

  1. Frontmatter

  2. 1. Basic Knowledge of the Electrolytic Capacitorless Motor drive

    Dawei Ding, Binxing Li, Qiwei Wang, Gaolin Wang, Guoqiang Zhang, Dianguo Xu
    Abstract
    Electrolytic capacitorless motor drives have many advantages such as high power density and reliability, since slim film capacitors are applied in the DC-link. However, the challenges of system harmonics and voltage utilization are need to be solved urgently.

  3. 2. Impedance Model of Reduced DC-Link Capacitance IPMSM Drives

    Dawei Ding, Binxing Li, Qiwei Wang, Gaolin Wang, Guoqiang Zhang, Dianguo Xu
    Abstract
    In order to solve the harmonic issue both in grid and motor side, the impedance model of the motor drive is analyzed in this chapter. The characteristics of the drive is well displayed through refined modeling with the consideration of non-ideal factors and so on.

  4. 3. Power Quality Improvement Methods on the Grid Side

    Dawei Ding, Binxing Li, Qiwei Wang, Gaolin Wang, Guoqiang Zhang, Dianguo Xu
    Abstract
    The LC resonance causes additional harmonics in the grid current. To solve this problem, some effective methods are investigated based on the system impedance model in this chapter, especially when the value of the DC-link inductance is low.

  5. 4. Grid Current Improvement Strategy Under Non-ideal Grid Conditions

    Dawei Ding, Binxing Li, Qiwei Wang, Gaolin Wang, Guoqiang Zhang, Dianguo Xu
    Abstract
    Due to the reduction of the DC-link capacitance, the drive system is sensitive to the grid. This chapter improves grid-side power quality under non-ideal grid conditions from two perspectives to enhancing the robustness and anti-interference capability of the drive in non-ideal grid.

  6. 5. Motor Side Beat Phenomenon Suppression Method

    Dawei Ding, Binxing Li, Qiwei Wang, Gaolin Wang, Guoqiang Zhang, Dianguo Xu
    Abstract
    The interaction between the fundamental component and harmonics of the motor current produce the beat phenomenon, which increases the operating noise. This chapter studies the beat suppression method based on the delay compensation and impedance reshaping to improve the quality of motor operation.

  7. 6. Overmodulation Methods with Low Distortion

    Dawei Ding, Binxing Li, Qiwei Wang, Gaolin Wang, Guoqiang Zhang, Dianguo Xu
    Abstract
    In this chapter, the switching aliasing caused by the fluctuation of DC-link voltage and reference voltage vector is solved by optimizing the overmodulation voltage boundary, and the operation effect of the drive system in the overmodulation region is improved.

  8. 7. Linear Modulation Region Expansion Strategy

    Dawei Ding, Binxing Li, Qiwei Wang, Gaolin Wang, Guoqiang Zhang, Dianguo Xu
    Abstract
    Reducing the fluctuation of the modulation index can prevent the drive from entering the overmodulation region in advance, and improve the voltage utilization of the drive during the operation of the linear region. In this chapter, a linear modulation margin enhancement strategy is proposed to improve the voltage utilization of the drive by suppressing the harmonics of modulation index.
