Description
Building on the tradition of its classic first edition, the long-awaited second edition of Elements of Power Electronics provides comprehensive coverage of the subject at a level suitable for undergraduate engineering students, students in advanced degree programs, and novices in the field. It establishes a fundamental engineering basis for power electronics analysis, design, and implementation, offering broad and in-depth coverage of basic material.
Streamlined throughout to reflect new innovations in technology, the second edition also features updates on renewable and alternative energy.
Elements of Power Electronics features a unifying
framework that includes the physical implications of circuit laws, switching circuit analysis, and the basis for converter operation and control. It discusses dc-dc, ac-dc, dc-ac, and ac-ac conversion tasks and principles of resonant converters and discontinuous converters. The text also addresses magnetic device design, thermal management and drivers for power semiconductors, control system aspects of converters, and both small-signal and geometric controls.
Models for
real devices and components-including capacitors, inductors, wire connections, and power semiconductors-are developed in depth, while newly expanded examples show students how to use tools like Mathcad,
Matlab, and Mathematica to aid in the analysis and design of conversion circuits.
Features:
*More than 160 examples and 350 chapter problems support the presented concepts
*An extensive Companion Website includes additional problems, laboratory materials, selected solutions for students, computer-based examples, and analysis tools for Mathcad, Matlab, and Mathematica

"Elements of Power Elements is a classic text, with modern examples that upgrade its relevance. It is an excellent first book on the subject, but also a reference that I use time and time again."--Robert Balog, Texas A&M University"This is an essential textbook by a world-class author. Its greatest strength is that it does not compromise on any of the important technical breadth and depth aspects. The revision is timely and enhances some important materials including applications and examples."--Martin Ordonez, University of British Columbia
"This book is the result of years of dedication and hard work by a superb educator. I commend him for his tenacity and attention to detail."--R. Ramakumar, Oklahoma State University
