Substantially expanded and updated, the new edition of this classic textbook provides unrivalled coverage of the fundamentals of power electronics. Comprehensive coverage of foundational concepts in circuits, magnetics, devices, dynamic modeling, and control establishes a strong conceptual framework for further study. Extensive discussion of contemporary practical considerations, enhanced by real-world examples, prepares readers for design scenarios ranging from low-power DC/DC converters to multi-megawatt AC machine drives or VHF power supplies. New topics include SiC and GaN wide bandgap materials, MOSFET and IGBT devices, multi-level converters, space-vector modulation, switched-capacitor converters, VHF converter circuits, and EMI. Over 300 new and revised end-of-chapter problems enhance and expand understanding of the material, with solutions for instructors. Unique in its breadth and depth, and providing a range of flexible teaching pathways at multiple levels, this is the definitive guide to power electronics for senior undergraduate and graduate students in electrical engineering, and practicing electrical engineers.
