This book focuses on the advanced control of reduced dc-link capacitance AC motor drives. Compared with the conventional AC motor drives, the reduced DC-link capacitance motor drives could reduce the cost, enhance the reliability and improve the power density. The control strategies proposed in this book are verified by experimental results, which include high power factor control, drive system stability control, beat phenomenon suppression, enhanced flux-weakening control, anti-overvoltage control, etc. The major features of this book are the systematic analysis, effective and optimized control of the practical issues in industry application, which could help readers to learn the reduced dc-link capacitance PMSM drives and promote the drive system application. This book could benefit researchers, engineers, and students in the field of AC motor drives.

This book focuses on the control strategies for gearless permanent magnet synchronous motor traction elevators. Both basic principles and experimental evaluation have been addressed. This is achieved by providing in-depth study on a number of major topics such as speed detection at low-speed operation, starting torque strategy based on dichotomy and staircase methods, fuzzy self-tuning method, MPC and ADRC, etc. The comprehensive and systematic treatment of control strategies for cost-effective gearless PMSM traction elevators and practical issues are the major features of the book, which is particularly suited for readers who are interested to learn the control strategies for cost-effective gearless PMSM traction elevators. The book benefits researchers, engineers, and graduate students in the fields of ac motor drives and control strategies for cost-effective gearless PMSM traction elevators, etc.

This book analyzes multi-MHz high frequency resonant DC-DC power converters with operating frequencies ranging from several MHz to tens of MHz in detail, aiming to support researchers and engineers with a focus on multi-MHz high frequency converters. The inverter stage, rectifier stage, matching network stage are analyzed in detail. Based on the three basic stages, typical non-isolated and isolated resonant DC-DC converters are depicted. To reduce the high driving loss under multi-MHz, resonant driving methods are introduced and improved. Also, the design and selection methods of passive and active component under multi-MHz frequency are described, especially for aircore inductor and transformer. Furthermore, multi-MHz resonant converter provides an approach for achieving flexible system.
