The Switched Reluctance Machine (SRM)is the least expensive electrical machine to produce, yet one of the most reliable. As such, research has blossomed during the last decade, and the SRM and variable drive systems using SRMs are receiving considerable attention from industry. However, successful realization of an SRM variable drive system demands an understanding of the converter and controller subsystems and their integration with the machine. Switched Reluctance Motor Drives provides that understanding a unified view of the machine and its drive system from all of its system and subsystem aspects. With a careful balance of theory and implementation, the author develops the analysis and design of SRMs from first principles, introduces a wide variety of power converters available for driving the SRM, and systematically presents both low and high-performance controllers.The book includes an in depth study of Power converters and controllers SRM drives enables readers to learn all aspects of SRM drive systems and apreciate the interdependence of the various subsystems in performance optimization.
