Principles Of Power Electronics

Substantially expanded and updated, the new edition of this classic provides unrivaled coverage of the fundamentals of power electronics. Unique in its breadth and depth, this is the definitive guide to power electronics for senior undergraduate and graduate students, and practicing electrical engineers.

This textbook offers broad coverage of the subject of power electronics. Each topic is developed in sufficient depth to expose the fundamental principles, concepts, techniques, methods, and circuits necessary to understand power electronic systems. The applications are diverse enough to expose students to numerous types of systems. The authors have paid particular attention to developing examples and exercises that promote innovative ways of thinking about problems, methods of analysis, and the use of approximations.

Power electronics became an identifiably separate area of electrical engineering with the invention of the thyristor about 30 years ago. The growing demand for controllability and conversion of electric energy has made this area increasingly important, which in turn has resulted in new device, circuit and control developments. In particular, new components, such as the GTO and power MOSFET, continue to extend power electronic technology to new applications. The technology embodied by the name "power electronics" is complex. It consists of both power level and signal level electronics, as well as thermal, mechanical, control, and protection systems. The power circuit, that part of the system actually processing energy, can be thought of as an amplifier around which is placed a closed loop control system. The goal of this book is to provide an easily understood exposition of the principles of power electronics. Common features of systems and their behavior are identified in order to facilitate understanding. Thyristor converters are distinguished and treated according to their mode of commutation. Circuits for various converters and their controls are presented, along with a description of ancillary circuits such as those required for snubbing and gate drives. Thermal and electrical properties of semiconductor power devices are discussed. The line-converter and converter-load interfaces are examined, leading to some general statements being made about energy transfer. Application areas are identified and categorized with respect to power and frequency ranges. The many tables presented in the book provide an easily used reference source.

An accessible introduction to all important aspects of electric machines, covering dc, induction, and synchronous machines. Also addresses modern techniques of control, power electronics, and applications. Exposition builds from first principles, making this book accessible to a wide audience. Contains a large number of problems and worked examples.

Designed for polytechnic and undergraduate students of electrical/electronics, this book offers short questions and answers at the end of chapters. It is also suitable for those preparing for professional courses like AMIE and AMITE.

This text provides an introduction to the field of power electronics, emphasizing real-world applications. It covers topics such as: power quality and vector control; power semiconductor devices; multiphase choppers and PWM inverters; and adjustable speed AC and DC motor drives.

Power Electronics Basics: Operating Principles, Design, Formulas, and Applications provides fundamental knowledge for the analysis and design of modern power electronic devices.

This book is aimed at people who want to understand how AC inverter drives work and how they are used in industry. This book is much more about the practical design and application of drives than about the mathematical principles behind them. The key principles of power electronics are described and presented in a simple way, as are the basics of both DC and AC motors. The detailed electronics of DC and AC drive are explained, together with the theoretical background and the practical design issues such as cooling and protection. An important part of the book gives details of the features and functions often found in AC drives, and gives practical advice on how and where to use these. A wide range of drive applications are described from fresh water pumping to baggage handling systems. The practical problems of using AC drives in industry are presented, and together with the application and function descriptions should prove useful and informative.
