Download or read book Application des Bond graphs la mod lisation et la commande de r seaux lectriques structure variable written by Roberto Sanchez and published by . This book was released on 2010 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse étudie les problèmes liés à l'association des principaux composants des réseaux électriques.La nature inductive des éléments à connecter pose des problèmes lors de leur association dans un nœud de connexion commun. Deux solutions sont proposées pour résoudre ce problème et rendre ainsi possible la simulation. Une première solution accepte la présence de causalités dérivées, la deuxième consiste à simplifier les modèles en supprimant localement les régimes dynamiques pour faciliter leur association.La mise en évidence graphique de la causalité dans le modèle global d'un micro réseau à structure variable montre que différentes configurations sont possibles, avec pour chacune un comportement et un fonctionnement différents pour les composants. L'outil bond graph a été choisi pour la modélisation des différents éléments, l'analyse des propriétés des modèles et la conception de lois de commande par modèle inverse à l'aide de la bicausalité. La robustesse de la commande pour le convertisseur d'électronique de puissance est analysée d'une manière classique pour tester ses performances par rapport aux incertitudes paramétriques, en faisant varier la charge connectée au convertisseur. La commande est validée par simulation et de manière expérimentale.

Download or read book Introduction to Power Electronics written by Paul H. Chappell and published by Artech House. This book was released on 2013-12-01 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of power electronics is concerned with solid state devices for the control and conversion of electrical power. These silicon devices are designed mainly for switching the transfer current from one part of an electrical circuit to another. Power electronics has a wide range of applications from the small systems used in electrical appliances to very large systems for the supply and distribution of electricity. Although it can be difficult to completely define where the boundary lies between electronics and power electronics, this resource succeeds at breaking down the discipline. Containing the useful concepts and building blocks that go into making a power converter operate successfully, this book provides a description of the characteristics of different types of power semiconductor devices and their application to power converter circuits. Applications to power transmission, electric drives, and medical equipment are included to illustrate the wide range of power electronics in both small and high power circuits.

Download or read book Circuits for Electronic Instrumentation written by Thomas Henry O'Dell and published by Cambridge University Press. This book was released on 1991-08-30 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an up-to-date text on electronic circuit design. The subject is dealt with from an experimental point of view, but this has not restricted the author to well-known or simple circuits. Indeed, some very recent and quite advanced circuit ideas are put forward for experimental work. Each chapter takes up a particular type of circuit, and then leads the reader on to gain an understanding of how these circuits work by proposing experimental circuits for the reader to build and make measurements on. This is the first book to take such a practical approach to this level. The book will be useful to final year undergraduates and postgraduates in electronics, practising engineers, and workers in all fields where electronic instrumentation is used and there is a need to understand electronics and the interface between the instrument and the user's own experimental system. The book's references will also be a very helpful guide to the literature.

Available in PDF, EPUB and Kindle. Book excerpt: Concisely covers all the important concepts in an easy-to-understand way Gaining a strong sense of signals and systems fundamentals is key for general proficiency in any electronic engineering discipline, and critical for specialists in signal processing, communication, and control. At the same time, there is a pressing need to gain mastery of these concepts quickly, and in a manner that will be immediately applicable in the real word. Simultaneous study of both continuous and discrete signals and systems presents a much easy path to understanding signals and systems analysis. In A Practical Approach to Signals and Systems, Sundararajan details the discrete version first followed by the corresponding continuous version for each topic, as discrete signals and systems are more often used in practice and their concepts are relatively easier to understand. In addition to examples of typical applications of analysis methods, the author gives comprehensive coverage of transform methods, emphasizing practical methods of analysis and physical interpretations of concepts. Gives equal emphasis to theory and practice Presents methods that can be immediately applied Complete treatment of transform methods Expanded coverage of Fourier analysis Self-contained: starts from the basics and discusses applications Visual aids and examples makes the subject easier to understand End-of-chapter exercises, with a extensive solutions manual for instructors MATLAB software for readers to download and practice on their own Presentation slides with book figures and slides with lecture notes A Practical Approach to Signals and Systems is an excellent resource for the electrical engineering student or professional to quickly gain an understanding of signal analysis concepts - concepts which all electrical engineers will eventually encounter no matter what their specialization. For aspiring engineers in signal processing, communication, and control, the topics presented will form a sound foundation to their future study, while allowing them to quickly move on to more advanced topics in the area. Scientists in chemical, mechanical, and biomedical areas will also benefit from this book, as increasing overlap with electrical engineering solutions and applications will require a working understanding of signals. Compact and self contained, A Practical Approach to Signals and Systems be used for courses or self-study, or as a reference book.
Download or read book A Foundation in Digital Communication written by Amos Lapidoth and published by Cambridge University Press. This book was released on 2009-07-09 with total page 750 pages. Available in PDF, EPUB and Kindle. Book excerpt: This intuitive yet rigourous introduction derives the core results of digital communication from first principles. Theory, rather than industry standards, motivates the engineering approaches, and key results are stated with all the required assumptions. The book emphasizes the geometric view, opening with the inner product, the matched filter for its computation, Parseval's theorem, the sampling theorem as an orthonormal expansion, the isometry between passband signals and their baseband representation, and the spectral-efficiency optimality of quadrature amplitude modulation (QAM). Subsequent chapters address noise, hypothesis testing, Gaussian stochastic processes, and the sufficiency of the matched filter outputs. Uniquely, there is a treatment of white noise without generalized functions, and of the power spectral density without artificial random jitters and random phases in the analysis of QAM. This systematic and insightful book, with over 300 exercises, is ideal for graduate courses in digital communication, and for anyone asking 'why' and not just 'how'.
