Opis

With today’s electrical and electronics systems requiring increased levels of performance and reliability, the design of robust EMI filters plays a critical role in EMC compliance. Using a mix of practical methods and theoretical analysis, EMI Filter Design, Third Edition presents both a hands-on and academic approach to the design of EMI filters and the selection of components values. The design approaches covered include matrix methods using table data and the use of Fourier analysis, Laplace transforms, and transfer function realization of LC structures. This edition has been fully revised and updated with additional topics and more streamlined content.

New to the Third Edition

• Analysis techniques necessary for passive filter realization
• Matrix method and transfer function analysis approaches for LC filter structure design
• A more hands-on look at EMI filters and the overall design process

Through this bestselling book’s proven design methodology and practical application of formal techniques, readers learn how to develop simple filter solutions. The authors examine the causes of common- and differential-mode noise and methods of elimination, the source and load impedances for various types of input power interfaces, and the load impedance aspect of EMI filter design. After covering EMI filter structures, topologies, and components, they provide insight into the sizing of components and protection from voltage transients, discuss issues that compromise filter performance, and present a goal for a filter design objective. The text also includes a matrix method for filter design, explains the transfer function method of LC structures and their equivalent polynomials, and gives a circuit design example and analysis techniques. The final chapter presents packaging solutions of EMI filters.

Recenzje

"This 3rd edition book is an excellent resource for solving EMI problems. It provides a systematic procedure for identifying noise sources and provides the design tools needed to solve problems. It will be an invaluable reference book for working electrical engineers as well as students who want to learn about EMI filtering and EMI noise problems. ... The book is filled with design equations that can be immediately put to use by the reader. This book can be a guidebook for diagnosing troublesome EMI issues in existing designs, and it can also be used to prevent EMI issues from occurring in the first place because of the information in this book. ... This is a book that should be used by every electrical engineer involved with EMI issues. It is filled with design equations, but more importantly it will provide you with an understanding of EMI issues, thus, making you a better design engineer."
