High-Frequency Magnetic Components (eBook)
John Wiley & Sons (Verlag)
9781118717783 (ISBN)
A unique text on the theory and design fundaments of inductors and transformers, updated with more coverage on the optimization of magnetic devices and many new design examples
The first edition is popular among a very broad audience of readers in different areas of engineering and science. This book covers the theory and design techniques of the major types of high-frequency power inductors and transformers for a variety of applications, including switching-mode power supplies (SMPS) and resonant dc-to-ac power inverters and dc-to-dc power converters. It describes eddy-current phenomena (such as skin and proximity effects), high-frequency magnetic materials, core saturation, core losses, complex permeability, high-frequency winding resistance, winding power losses, optimization of winding conductors, integrated inductors and transformers, PCB inductors, self-capacitances, self-resonant frequency, core utilization factor area product method, and design techniques and procedures of power inductors and transformers. These components are commonly used in modern power conversion applications. The material in this book has been class-tested over many years in the author’s own courses at Wright State University, which have a high enrolment of about a hundred graduate students per term. The book presents the growing area of magnetic component research in a textbook form, covering the foundations for analysing and designing magnetic devices specifically at high-frequencies. Integrated inductors are described, and the Self-capacitance of inductors and transformers is examined. This new edition adds information on the optimization of magnetic components (Chapter 5). Chapter 2 has been expanded to provide better coverage of core losses and complex permeability, and Chapter 9 has more in-depth coverage of self-capacitances and self-resonant frequency of inductors. There is a more rigorous treatment of many concepts in all chapters. Updated end-of-chapter problems aid the readers’ learning process, with an online solutions manual available for use in the classroom.
- Provides physics-based descriptions and models of discrete inductors and transformers as well as integrated magnetic devices
- New coverage on the optimization of magnetic devices, updated information on core losses and complex permeability, and more in-depth coverage of self-capacitances and self-resonant frequency of inductors
- Many new design examples and end-of-chapter problems for the reader to test their learning
- Presents the most up-to-date and important references in the field
- Updated solutions manual, now available through a companion website
An up to date resource for Post-graduates and professors working in electrical and computer engineering. Research students in power electronics. Practising design engineers of power electronics circuits and RF (radio-frequency) power amplifiers, senior undergraduates in electrical and computer engineering, and R & D staff.

Professor Marian K. Kazimierczuk, Wright State University, Dayton, Ohio, USA Professor Kazimierczuk has been conducting research in the area of power electronics amplifiers for more than thirty years, twice chairing the Technical Committee of Power Electronics and Power Systems for the IEEE Circuits and Systems Society. Over twenty-two years he has taught three graduate courses in high-frequency power electronics, and has won the Excellence in Teaching Award several times. His Science Citation index is one of the highest in the field, at over 1000 citations; he owns seven patents, has published over 110 papers in the IEEE Transactions, and has published more than 150 papers in the IEEE international conferences on power conversion. An IEEE Fellow, he has served as Associate Editor for the IEEE Transactions on Circuits and Systems and is currently an Associate Editor of the IEEE Transactions on Industrial Electronics.
"What sets this book apart from previous magnetics books recently reviewed in How2Power Today is its depth of coverage, especially of topics that are hard to analyze such as winding resistance caused by the skin and proximity effects, and parasitic winding capacitances. Kazimierczuk--I'll call him "Kaz" for short, as Apple co-founder Steve Wozniak is called "Woz"--has worked out in sufficient detail the mathematical derivations of design equations that usually appear in the literature as either given (or else ignored entirely) rather than derived." (How2Power.com, 1 September 2015)
"Loaded with essential formulas and design methods, this book will give the designer of high-frequency magnetic components not only a better design but will reinforce an understanding of the high-frequency magnetic component design." (IEEE Electrical Engineering magazine, 1 March 2015)
