Electromagnetic Compatibility in Power Electronics


Book Description

Electronics professionals will find this book invaluable when designing power equipment, because it describes in detail how to cope with the problem of electromagnetic interference. The author shows how to meet the exacting US and European EMC standards for conducted emissions. The book includes a wide range of EMI analysis techniques. An important focus is on the energy content of interference transient signals (traditional analysis concentrates on amplitude and frequency). This provides a more accurate picture of the EMI situation. For those who do not want or need detailed analysis techniques, many approximation methods are also provided. These simplified techniques give accurate results for all but the most stringent applications. The book contains several worked examples and an extensive bibliography, and is sure to be useful to electronic design engineers and others who need to meet international EMC regulations and standards. Laszlo Tihanyi has worked on EMC for over 20 years. Formerly Head of the Department of Power Electronics at the Hungarian Research Institute for the Electrical Industry, he focused primarily on solving EMI problems in electronic systems and developing a dimensioning method for power line filters.

Cable Shielding for Electromagnetic Compatibility


Book Description

The mathematical theory of wave propagation along a conductor with an external coaxial return is very old, going back to the work of Rayleigh, Heaviside, and J. J. Thomson. These words were written by S. A. Schelkunoff back in 1934. Indeed, those early works dealt with signal propagation along the line as well as electromagnetic shielding of the environment inside and/or outside the metallic enclosures. Max well himself developed pioneering studies of single-layer shielding shells, while a paper with such a "modern" title as "On the Magnetic Shielding of Concentric Spherical Shells" was presented by A. W Rucker as early as 1893! * Such "state of the art" shielding theory created in the last century is even more amazing if you think that at almost the same time (namely, in 1860s), a manuscript of Jules Verne's book, Paris in the. xx Century, was rejected by a publisher because it pre dicted such "outrageously incredible" electrotechnology as, for example, FAX service by wires and the electrocutioner's chair. (With regard to the last invention, I suspect many readers would rather Jules Verne has been wrong. ) However, although the beginning of electromagnetic shielding theory and its implementation to electronic cables date back more than a century, this dynamic field keeps constantly growing, driven by practical applications.




EMC for Product Designers


Book Description

EMC for Product Designers: Meeting the European EMC Directives is a six-chapter text that considers the by-product of the co-existence of all kinds of radio services, called electromagnetic compatibility (EMC). This book discusses the solution to the damaging frequency interference of EMC and the problem of EMC to electronic equipment. The opening chapter considers the effect of adapting the EMC Directives to decrease the economic damage being caused by electromagnetic interference, as well as the analysis, definition, and compliance of EMC and EMC Directives. The next chapters deal with the measurement of EMC; RF emission testing; features of circuits, layout, and grounding; digital and analogue circuit design; and description of interfaces, filtering, and shielding. These topics are followed by discussion of the equipment for mains harmonic emission, the facilities and equipment for measuring RF susceptibility, and the transient susceptibility to ESD. The concluding chapters examine the use of performance criteria in measuring EMC. These chapters describe the features and application of the Fourier spectrum. The book can provide useful information to economists, engineers, radio technicians, students, and researchers.
