Electrolytic Capacitorless Permanent Magnet Synchronous Motor Drives

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.
