Electric Drives

Electric Drives, now in its fourth 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 and phones to robots, electric transport, industrial processes, and modern distributed electric power systems with ever more renewable energy penetration. Every proposition, number, figure, and reference has been revisited to bring necessary changes, with new references to key recent knowledge trends, to reflect the present state of the art. The book has been restructured, with a few chapters combined and one chapter (on rectifier d.c. brush motor drives) removed, new introductory paragraphs in most chapters (many as inspiring case studies), and brand-new chapters on flux-modulation machine drives (Chapter 8) and predictive control of a.c. drives (Chapter 15), reflecting this updating effort. The large number of new case studies complements the large number of worked numerical examples and the 10 user-friendly MATLAB® and Simulink® programs that remain available online. Although, inevitably, the math is intensive and intended to be directly usable, the book, mainly intended for senior undergraduate and graduate students and engineers in research and development in industry, is a practical, easy-to-assimilate, and up-to-date synthesis of basic and advanced power electronics (variable speed) electric motor-generator drives needed in all industries in which electric energy flow-wise, mainly digitally intelligent, control is paramount.

Prof. Ion Boldea (IEEE Life Fellow) studied at and obtained a PhD in electrical engineering (on linear induction motors design and control) in 1973 at University Politehnica Timisoara, Romania. He has been an active professor since 1968, having completed a Fulbright postdoctoral scholarship in the United States (1973-1974). Over the years, he has spent more than five years as a visiting professor at institutions across the United States, the United Kingdom, Denmark, and South Korea. He investigated and published extensively on linear and rotary electric machine drives and magnetically levitated vehicles (MAGLEVs), focusing on their design and control for industrial applications, with his work appearing primarily in IEEE papers and books. In recognition of his professional contributions, he received the 2015 Nikola Tesla IEEE Award and the 2021 EPE Outstanding Achievement Award. He is a full member of both the Romanian Technical Sciences Academy and the Romanian Academy, and holds a Doctor Honoris Causa from Aalborg University, Denmark. Prof. Boldea has given numerous keynote addresses at IEEE-sponsored international conferences and has delivered (as an IEEE-IAS Distinguished Lecturer since 2008) numerous intensive courses and lectures in the United States, Denmark, South Korea, Brazil, and Italy, among other countries. He chaired and co-chaired the biannual IEEE-sponsored international conference, OPTIM-ACEMP, for over 30 years. He has also held tech consulting contracts with international companies for decades and co-founded the company Bee-Speed (www.Bee-Speed.ro) in 1994, which is still continually active today, specializing in industrial digital electric automation in water integrated technologies. He enjoys a rich family life and studies seminal books in philosophy, literature, economics, math, and physics. He rides his bicycle to work daily, and his hobbies include gardening and tennis.
