Emc In Power Electronics

Scientists largely attribute the recent deterioration of the electromagnetic environment to power electronics. This realization has spurred the study of methodical approaches to electromagnetic compatibility designs as explored in this text. The book addresses major challenges, such as handling numerous parameters vital to predicting electro magnetic effects and achieving compliance with line-harmonics norms, while proposing potential solutions.

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.

A large amount of natural or artificially produced physical phenomena are exploited for practical applications, even though several of them give rise to unpleasant consequences. These ultimately manifest themselves under form of malfunction or definitive failure of components and systems, or environmental hazard. So far, manifold categories of inadvertent or deliberate sources have been discovered to simultaneously produce useful effects in some ways but adverse ones in others. In particular, responsible for the growing interest in the last decades for Electromagnetic Compatibility (EMC) has been the progressive miniaturisation and sensitivity of electronic components and circuits, often operating in close proximity to relatively powerful sources of electromagnetic interference. Potential authors of books on the subject-matter are fully aware of the fact that planning production of manageable handbooks capable to treat all the EMC case studies of practical and long-lasting interest could result in a questionable and difficult undertaking. Therefore, in addition to textbooks providing a thorough background on basic aspects, thus being well-tailored for students and those which want to get in contact with this discipline, the most can be made to jointly sustain a helpful and practicable publishing activity is to supply specialised monographs or miscellanies of selected topics. Such resources are preferentially addressed to post-graduate students, researchers and designers, often employed in the forefront of research or engaged for remodelling design paradigms. Hence, the prerequisite for such a class of publications should consist in arousing critical sense and promoting new ideas. This is the object of Electromagnetic Compatibility in Power Systems, which tries to rather discuss special subjects, or throw out suggestions for reformulating conventional approaches, than to appear as a reference text. A common motivation encouraged the contributors to bringing together a number of accounts of the research that they have undertaken over the late years: willing to fill the important need of covering EMC topics rather proper to transmission and distribution of electric power than, more usually, to Electronics and Telecommunication Systems. EMC topics for Power Systems, at last! Investigating EMC features of distributed and/or complex systems A broad body of knowledge for specific applications A stimulating support for those which are engaged in the forefront of research and design An example of how breaking ideas should be encouraged and proudly applied A fruitful critique to overcomplicated and unpractical models A comprehensive resource to estimate the important role of EMC at lower frequencies

“Power Electronics in Smart Electrical Energy Networks” introduces a new viewpoint on power electronics, re-thinking the basic philosophy governing electricity distribution systems. The proposed concept fully exploits the potential advantages of renewable energy sources and distributed generation (DG), which should not only be connected but also fully integrated into the distribution system in order to increase the efficiency, flexibility, safety, reliability and quality of the electricity and the networks. The transformation of current electricity grids into smart (resilient and interactive) networks necessitates the development, propagation and demonstration of key enabling cost-competitive technologies. A must-read for professionals in power engineering and utility industries, and researchers and postgraduates in distributed electrical power systems, the book presents the features, solutions and applications of the power electronics arrangements useful for future smart electrical energy networks.

Praise for Noise Reduction Techniques IN electronic systems "Henry Ott has literally 'written the book' on the subject of EMC. . . . He not only knows the subject, but has the rare ability to communicate that knowledge to others." —EE Times Electromagnetic Compatibility Engineering is a completely revised, expanded, and updated version of Henry Ott's popular book Noise Reduction Techniques in Electronic Systems. It reflects the most recent developments in the field of electromagnetic compatibility (EMC) and noise reduction¿and their practical applications to the design of analog and digital circuits in computer, home entertainment, medical, telecom, industrial process control, and automotive equipment, as well as military and aerospace systems. While maintaining and updating the core information—such as cabling, grounding, filtering, shielding, digital circuit grounding and layout, and ESD—that made the previous book such a wide success, this new book includes additional coverage of: Equipment/systems grounding Switching power supplies and variable-speed motor drives Digital circuit power distribution and decoupling PCB layout and stack-up Mixed-signal PCB layout RF and transient immunity Power line disturbances Precompliance EMC measurements New appendices on dipole antennae, the theory of partial inductance, and the ten most common EMC problems The concepts presented are applicable to analog and digital circuits operating from below audio frequencies to those in the GHz range. Throughout the book, an emphasis is placed on cost-effective EMC designs, with the amount and complexity of mathematics kept to the strictest minimum. Complemented with over 250 problems with answers, Electromagnetic Compatibility Engineering equips readers with the knowledge needed to design electronic equipment that is compatible with the electromagnetic environment and compliant with national and international EMC regulations. It is an essential resource for practicing engineers who face EMC and regulatory compliance issues and an ideal textbook for EE courses at the advanced undergraduate and graduate levels.

If the operation of electronic components switching scheme to reduce congestion and losses (in power converters in general and switching power supplies in particular), it also generates electromagnetic type of pollution in its immediate environment. Power Electronics for Industry and Transport, Volume 4 is devoted to electromagnetic compatibility. It presents the sources of disturbance and the square wave signal, spectral modeling generic perturbation. Disturbances propagation mechanisms called "lumped" by couplings such as a common impedance, a parasitic capacitance or a mutual and "distributed constant", for which the spatial-temporal character must be taken into account, are also covered. This book also provides spectral analysis among other items that contain inequality Heisenberg-Gabor, very useful for understanding the spread spectrum PWM type signals.
