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

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.

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.
A railway is a complex distributed engineering system: the construction of a new railway or the modernisation of a existing one requires a deep understanding of the constitutive components and their interaction, inside the system itself and towards the outside world. The former covers the various subsystems (featuring a complex mix of high power sources, sensitive safety critical systems, intentional transmitters, etc.) and their interaction, including the specific functions and their relevance to safety. The latter represents all the additional possible external victims and sources of electromagnetic interaction. EMC thus starts from a comprehension of the emissions and immunity characteristics and the interactions between sources and victims, with a strong relationship to electromagnetics and to system modeling. On the other hand, the said functions are achieved and preserved and their relevance for safety is adequately handled, if the related requirements are well posed and managed throughout the process from the beginning. The link is represented by standards and their correct application, as a support to analysis, testing and demonstration.

The Electromagnetic Compatibility has become an increasingly essential factor for placing a product on the global, world wide market. Fulfilling emission limits and immunity requirements as well as handling apparently complex cases of incompatibility demands a deeper understanding of the physical interrelations and of Maxwell's theory. Based on the authors’ experiences, the textbook provides some help in solving such interferential cases. It contains many illustrative examples and more than 80 exercises with solutions.
The integration of electronics in large systems and installations steadily increases, consider for example the emergence of the Industrial Internet of Things. Power consumption decreases while the operating speed increases making equipment potentially more vulnerable for interference. The responsibility of the installer is shifting towards that of the system integrator, requiring more in-depth knowledge to achieve and maintain EMC during the technical and economical lifespan of the system or installation and the distinction between both diminishes. EMC for Installers: Electromagnetic Compatibility of Systems and Installations combines an integral risk based approached to EMC design and management with robust technical measures. Written by two experts, who both started nearly three decades ago in EMC, it provides guidance to those new in the field and servers as reference to those with experience. The book starts with the basic concept of EMC and evolves gradually towards more difficult topics. Particular attention is given to grounding concepts and the protection of cabling and wiring. This book puts a strong focus on passive means that are widely available for each installer: cable conduits used for cable routing can be exploited for significant improvement of the EMC-behavior of the system or installation. In addition, it will be explained how to use standard metallic enclosures to enhance the EMC-performance. For most demanding situations shielded rooms and shielding cabinets are explained. This book describes pre-compliance and full-compliance testing tailored to large systems. Templates and checklists are provided for both risk and management and test management. Electromagnetic compatibility explained as simple as possible, without over-simplifying. Practical approach, with hands-on demonstrations based on an example installation. Learn how to exploit cable conduits, used for cable routing anyway, to improve the EMC performance of an installation. Learn how to exploit standard metallic enclosures to improve EMC in systems. Design of power distribution networks to minimize disturbing fields. Toolbox and templates for managing and sustaining EMC over a long lifetime.
As the number of electrical devices in use continues to grow, so do the challenges of ensuring the electromagnetic compatibility (EMC) of products and systems. Fortunately, engineers have at their disposal an array of approximations, models, and rules-of-thumb to help them meet those challenges. Unfortunately, the number of these tools and guidelines is overwhelming, and worse still is the thought of investigating their origins and confirming their results. The Electromagnetic Compatibility Handbook is an unprecedented compilation of the many approximations, guidelines, models, and rules-of-thumb used in EMC analyses, complete with their sources and their limitations. The book presents these in an efficient question-and-answer format and incorporates an extremely comprehensive set of tables and figures. The author has either derived from basic principles or obtained and verified from their original sources all of the expressions in the tables. Mathcad was used to generate most of the plots and solve many of the equations, and the author includes the Mathcad programs for many of these so users can clearly see the variable assignments, assumptions, and equations. Designed to be of long-lasting value to engineers, researchers, and students, the Electromagnetic Compatibility Handbook is ideal both for quick reference and as a textbook for upper-level and graduate electrical engineering courses.
