About Of The Book :
"Elements of Power Electronics" is a book written by Dr. Philip T. Krein, a professor of Electrical and Computer Engineering at the University of Illinois at Urbana-Champaign. The book is intended as a textbook for undergraduate and graduate courses in power electronics.
The book covers a broad range of topics related to power electronics, including power semiconductor devices, power conversion circuits, DC-DC converters, AC-DC converters, motor drives, power quality, and renewable energy systems. The book emphasizes the practical aspects of power electronics design and provides numerous examples and design exercises to reinforce the concepts presented.
One of the strengths of "Elements of Power Electronics" is its clear and concise writing style, which makes complex topics accessible to students with a solid background in circuit analysis and electronics. The book also includes many diagrams and illustrations to help visualize the concepts presented.
Overall, "Elements of Power Electronics" is a well-regarded and widely used textbook in the field of power electronics, suitable for both students and practicing engineers who want to deepen their knowledge in this area.
Power electronics is one of the broadest growth areas in electrical technology. Today, electronic energy processing circuits are needed for every computer system, every digital product, industrial systems of all types, automobiles, home appliances, lamps, lighting equipment, motor controllers, and just about every possible application of electricity. At one time, the growth was pushed by energy conservation goals. Today, there are many more benefits in terms of reliable, lightweight power processors. A host of new applications is made possible by improvements in semiconductors and by a better understanding of power electronics. Motors with integrated electronic controls will soon be the norm. Portable telephones and communication devices demand tightly optimized power management. Advanced microprocessors need special techniques to supply their power. Utilities worry about the quality of their product, and about how to use electronics for more effective power delivery. This text presents modem power electronics in its many facets. But it is not a loose collection of information. Rather, the intent is to lay down a firm conceptual base from which engineers can examine the field and practice its unusual and challenging design problems. What makes the treatment different? First, a sound scientific framework is established, then students are encouraged to observe how the many converter types and methods branch out naturally from this framework. Second, the treatment is structured for aspiring student engineers. It is written to help students synthesize their electrical engineering study, as they finish an education and begin a career or advanced study. Third, it covers a great deal of support material, such as models for passive components and basic design strategies for magnetics, that is rarely taught but is ubiquitous for the practicing designer.
The book is organized into five parts. Four are here in your hands. Part V, the laboratory supplement, is available through a World Wide Web site. In Part, I, the framework for power electronics is established. The three chapters in Part I offer a historical perspective, and establish key framework concepts such as switching functions, equivalent methods for filter design, diode circuit analysis, and regulation. Part I1 covers all the major converter classesdc-dc, ac-dc, dc-ac, ac-ac, and resonant converters in considerable depth. Students are often surprised to learn that they can become effective designers of useful converters by the time they are through Chapter 4. Chapter 8 presents perhaps the first undergraduate text material on the emerging subject of resonant converters. Part I11 covers the issues of components, from models for sources and loads to power semiconductors to the circuits that drive them. Unique features include the fundamental approach to magnetics design, coverage of wire sizing and parasitic resistance effects, and extensive examples. Part IV introduces control methods, again at the undergraduate level. Chapters 15 and 16 discuss general control issues and develop the popular frequency domain design approach. Chapter 17 provides a new perspective on an especially simple approach to large-signal control. The book is big because of the breadth of the field. The general layout supports a first PREFACE xv course at the senior level, based on Part I and Part 11. A second course would cover Part I11 and Part IV. At the University of Illinois, there is just one course at present. We attempt to cover Chapters 1-6, 11, and 12 in detail, with briefer treatments of 7-10 and 13-14. The chapters are relatively independent, so a variety of course arrangements can be supported. As prerequisites, students should recognize that all their basic coursework in electrical engineering will be brought to bear for the study of power electronics. Prior courses in circuits, electronics, systems, and electromagnetics are essential. Prior courses in electromechanics, analog or digital circuit and filter design, and power systems can be helpful but are not vital. A few things are not here. Space and time do not permit detailed coverage of individual applications. Motor control and telecommunications power are two examples. It is not possible to provide adequate coverage for dc or ac motor control, or for telecommunications power system design. Beyond the introduction in Chapter 6, the motor control application is left to books from others. The telecommunications application is left to a number of dc4c converter examples. The book makes extensive use of computer tools, and students are encouraged to follow this lead. However, no floppy disk is included because few readers find time to learn the programs on such disks. Instead, several example listings are given in the Appendix. Also, students may visit the Web site http://power.ece.uiuc.edu/krein-text to find copies of programs for downloading and to obtain updates to programs or course materials. A group of industry-based students developed extensive Mathcad@ applications. Some of these can be found on the site. Additional problems will be posted as well. Instructors can request Web access to problem solutions through the publisher.
