Switching theory is concerned with the development of models and techniques for the analysis and synthesis of those circuits in which information is represented in discrete or digital form, as opposed to the analog form in which information is represented in a continuous manner. The application of digital techniques over a wider range of human activities has already profoundly affected modern life, and there is no visible limit to their future utility. This book is the outgrowth of a course on switching circuits that the author has taught since 1960, and it is designed as a text to provide a unified treatment of the subject with particular emphasis on sequential circuit theory. An attempt has been made to include only those techniques that have been generally accepted and seem to have lasting application. The first four of the nine chapters are devoted to basic principles and to combinational circuit theory. They introduce number systems, binary codes, Boolean algebra, switching functions, the analysis and synthesis of combinational gate circuits (including NAND, NOR, EXCLUSIVE-OR, and EXCLUSIVE-NOR), and threshold logic, among other topics. Also covered are algebraic, geometric, and tabular techniques for the minimization of algebraic expressions. The remainder of this book is on sequential circuit theory. A general treatment is emphasized by classification of the sequential-circuit operation as either fundamental mode or pulse mode, and as either clocked or not clocked. A comparison of the two modes is enhanced by design examples in which the same problem specifications are used for each mode. Both algebraic and tablular techniques are presented for the analysis and synthesis of these circuits. The timely topics of control states and register transfers in sequential design are included. The book closes with a discussion of sequential-circuit minimization associated with the reduction of flow tables, and the state-assignment problem. Answers are provided to selected problems.

This book focuses on the theory and application of power switching components in power networks. More specifically, it discusses current interruption theory, applied stresses to switching components in power networks and appropriate methods to test their different functionalities. It reviews the basic working principles of current technologies and summarizes the upcoming technological advances within the field of power switching devices. Taking an educational approach to the subject, this book is useful for graduate courses on high voltage equipment and power device technology within the electric power engineering discipline. Furthermore, inclusion of numerous worked examples, exercises and easily digestible descriptions of complex physical phenomena in switching devices make this an invaluable self-learning resource for engineers.

This comprehensive text on switching theory and logic design is designed for the undergraduate students of electronics and communication engineering, electrical and electronics engineering, electronics and instrumentation engineering, telecommunication engineering, computer science and engineering, and information technology. It will also be useful to AMIE, IETE and diploma students. Written in a student-friendly style, this book, now in its Second Edition, provides an in-depth knowledge of switching theory and the design techniques of digital circuits. Striking a balance between theory and practice, it covers topics ranging from number systems, binary codes, logic gates and Boolean algebra to minimization using K-maps and tabular method, design of combinational logic circuits, synchronous and asynchronous sequential circuits, and algorithmic state machines. The book discusses threshold gates and programmable logic devices (PLDs). In addition, it elaborates on flip-flops and shift registers. Each chapter includes several fully worked-out examples so that the students get a thorough grounding in related design concepts. Short questions with answers, review questions, fill in the blanks, multiple choice questions and problems are provided at the end of each chapter. These help the students test their level of understanding of the subject and prepare for examinations confidently. NEW TO THIS EDITION • VHDL programs at the end of each chapter • Complete answers with figures • Several new problems with answers

The design of Switching Power Supplies has become one of the most crucial aspects of power electronics, particularly in the explosive market for portable devices. Unfortunately, this seemingly simple mechanism is actually one of the most complex and under-estimated processes in Power Electronics. Switching power conversion involves several engineering disciplines: Semiconductor Physics, Thermal Management, Control Loop theory, Magnetics etc, and all these come into play eventually, in ways hard for non-experts to grasp. This book grows out of decades of the author's experience designing commercial power supplies. Although his formal education was in physics, he learned the hard way what it took to succeed in designing power supplies for companies like Siemens and National Semiconductor. His passion for power supplies and his empathy for the practicing or aspiring power conversion engineer is evident on every page.* The most comprehensive study available of the theoretical and practical aspects of controlling and measuring Electromagnetic Interference in switching power supplies, including input filter instability considerations. * Step-by-step and iterative approach for calculating high-frequency losses in forward converter transformers, including Proximity losses based on Dowell's equations.* Thorough, yet uniquely simple design flow-chart for building DC-DC converters and their magnetic components under typical wide-input supply conditions * Step-by-step, solved examples for stabilizing control loops of all three major topologies, using either transconductance or conventional operational amplifiers, and either current-mode or voltage-mode control.

This new approach to an established field introduces the concept of predicate logic in order to supersede propositional logic in switching theory. The author gives new insight into the theory of latches (memory circuits) for use in undergraduate and graduate courses.
