Electric Drives

Electric Drives, now at 4th edition, provides a practical guide in understanding the fundamental principles and recent new knowledge of electric motion (in motoring) and electric energy flow (in generating) digital control via power electronics for energy savings and increased productivity in practically all industries, from intelligent watches, phones, to robots, electric transport, industrial processes, modern distributed electric power systems with ever more renewable energy penetration. Every proposition, number, figure, reference has been revisited to bring necessary changes Includes new references to key recent knowledge trends, to reflect the present status of the art. Includes new case studies that complement the large number of worked numerical examples and the 10 MATLAB - Simulink use-friendly programs that remain available online. A restructuring by unification of a few Chapters, the elimination of one Chapter (rectifier d.c. brush motor drives) and the introduction of new paragraphs in most Chapters (many as inspiring case studies) and a brand new Chapters on "Flux-modulation machine drives" (Chapter 8) and on "Predictive Control of a.c. drives" (Chapter 15), reflects this knowledge updating effort. Though inevitably math - intensive, to be directly usable, the book, mainly intended for senior undergraduate, graduate students and engineers in R&D in industry, is a practical, easy to assimilate, up-to-date synthesis of basic and advanced power electronics (variable speed) electric motor - generator drives needed in all industries where electric energy flow wise - mainly - digital intelligent, control is paramount.
