The switched reluctance machine (SRM) is the least expensive yet one of the most reliable electrical machines to produce and apply and, therefore, the focus of considerable industry attention. Engineers need to understand the integration of the machine, converter, and controller subsystems to succeed in developing SRM variable drive systems. This book thoroughly explores SRMs, their associated power converters and controllers, and their integration. It presents the analysis and design of SRMs from first principles, introduces a wide variety of converters available for driving SRMs, and develops a step-by-step procedure to model and simulate SRM drive systems.
