Download Introduction to Modern Power Electronics Third Edition by Andrzej M. Trzynadlowski easily in PDF format for free.


This text is primarily intended for a one-semester introductory course in power electronics at the undergraduate level. However, containing a comprehensive overview of modern tools and techniques of electric power conditioning, the book can also be used in more advanced classes. Practicing engineers wishing to refresh their knowledge of power electronics, or interested in branching into that area, are also envisioned as potential readers. Students are assumed to have working knowledge of the electric circuit analysis and basic electronics.




During the five years since the second edition of the book was published, power electronics has enjoyed robust progress. Novel converter topologies, applications, and control techniques have been developed. Utilizing advanced semiconductor switches, power converters reach ratings of several kilovolts and kiloamperes. The threat of unchecked global warming, various geopolitical and environmental issues, and the monetary and ecological costs of fossil fuels represent serious energy challenges, which set off intensive interest in sources of clean power. As a result, power electronic systems become increasingly important and ubiquitous. Changes made to this third edition reflect the dominant trends of modern power electronics.




They encompass the growing practical significance of PWM rectifiers, the Z-source dc link, matrix converters, and multilevel inverters, and their application in renewable energy systems and powertrains of electric and hybrid vehicles. In contrast with most books, which begin with a general introduction devoid of detailed information, Chapter 1 constitutes an important part of the teaching process. Employing a hypothetical generic power converter, basic principles and methods of power electronics are explained. Therefore, whatever content sequence an instructor wants to adopt, Chapter 1 should be covered first.




Chapters 2 and 3 provide description of semiconductor power switches and supplementary components and systems of power electronic converters. The reader should be aware of the existence and function of those auxiliary but important parts although the book is mostly focused on power circuits, operating characteristics, control, and applications of the converters. The four fundamental types of electrical power conversion—ac to dc, ac to ac, dc to dc, and dc to ac—are covered in Chapters 4 through 7, respectively. Chapters 4 and 7, on rectifiers and inverters, are the longest chapters, reflecting the great importance of those converters in modern power electronics. Chapter 8 is devoted to switching dc power supplies, and Chapter 9 covers applications of power electronics in clean energy systems. Each chapter begins with an abstract and includes a brief summary that follows the main body.




Numerical examples, homework problems, and computer assignments complement most chapters. Several relevant and easily available references are provided after each of them. Three appendices conclude the book. The textbook is accompanied by a series of forty-six PSpice circuit files constituting a virtual power electronics laboratory, and available at http://www.wiley .com/go/modernpowerelectronics3e. The files contain computer models of most power electronic converters covered in the book. The models are a valuable teaching tool, giving the reader an opportunity to tinker with the converters and visualize their operation. Another teaching tool, a PowerPoint presentation, which contains all figures, tables, and most important formulas, is also available, at http://www.wiley.com/go/modernpowerelectronics3e.




It will ease the instructor from drawing the often complex circuit diagrams and waveforms on the classroom board. Against most of the contemporary engineering textbooks, the book is quite concise. Still, covering the whole material in a single-semester course requires from the students a substantial homework effort. The suggested teaching approach would consist in presenting the basic issues in class and letting the students to broaden their knowledge by reading assigned materials, solving problems, and performing PSpice simulations.
