High-Frequency Magnetic Components

A unique text on the theory and design fundaments ofinductors and transformers, updated with more coverage on theoptimization of magnetic devices and many new designexamples

The first edition is popular among a very broad audience ofreaders in different areas of engineering and science. This bookcovers the theory and design techniques of the major types ofhigh-frequency power inductors and transformers for a variety ofapplications, including switching-mode power supplies (SMPS) andresonant dc-to-ac power inverters and dc-to-dc power converters. Itdescribes eddy-current phenomena (such as skin and proximityeffects), high-frequency magnetic materials, core saturation, corelosses, 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 factorarea product method, and design techniques and procedures of powerinductors and transformers. These components are commonly used inmodern power conversion applications. The material in this book hasbeen class-tested over many years in the author’s own coursesat Wright State University, which have a high enrolment of about ahundred graduate students per term. The book presents the growingarea of magnetic component research in a textbook form, coveringthe foundations for analysing and designing magnetic devicesspecifically at high-frequencies. Integrated inductors aredescribed, and the Self-capacitance of inductors and transformersis examined. This new edition adds information on the optimizationof magnetic components (Chapter 5). Chapter 2 has been expanded toprovide better coverage of core losses and complex permeability,and Chapter 9 has more in-depth coverage of self-capacitances andself-resonant frequency of inductors. There is a more rigoroustreatment of many concepts in all chapters. Updated end-of-chapterproblems aid the readers’ learning process, with an onlinesolutions manual available for use in the classroom.
