Public ISBD Titre : Power electronics for modern wind turbines Type de document : texte imprimé Auteurs : Frede Blaabjerg, Auteur ; Zhe Chen, Auteur Editeur : USA : Morgan & Claypool Publishers Année de publication : 2006 Collection : Synthesis Lectures ON Power Electronics Importance : 60 p. Présentation : couv. ill. en coul., ill. Format : 24 cm. ISBN/ISSN/EAN : 978-1-598-29032-5 Langues : Anglais (eng) Catégories : LES ÉNERGIES Index. décimale : 21-06 L'énergie éolienne Résumé : Wind energy is now the world's fastest growing energy source. In the past 10 years, the global wind energy capacity has increased rapidly. The installed global wind power capacity has grown to 47.317 GW from about 3.5 GW in 1994. The global wind power industry installed 7976 MW in 2004, an increase in total installed generating capacity of 20%. The phenomenal growth in the wind energy industry can be attributed to the concerns to the environmental issues, and research and development of innovative cost-reducing technologies.Denmark is a leading producer of wind turbines in the world, with an almost 40% share of the total worldwide production. The wind energy industry is a giant contributor to the Danish economy. In Denmark, the 3117 MW (in 2004) wind power is supplied by approximately 5500 wind turbines. Individuals and cooperatives own around 80% of the capacity. Denmark will increase the percentage of energy produced from wind to 25% by 2008, and aims for a 50% wind share of energy production by 2025.Wind technology has improved significantly over the past two decades, and almost all of the aspects related to the wind energy technology are still under active research and development. However, this monograph will introduce some basics of the electrical and power electronic aspects involved with modern wind generation systems, including modern power electronics and converters, electric generation and conversion systems for both fixed speed and variable speed systems, control techniques for wind turbines, configurations of wind farms, and the issues of integrating wind turbines into power systems.

Design and Development of RFID and RFID-Enabled Sensors on Flexible Low Cost Substrates / Li Yang

Public ISBD Titre : Design and Development of RFID and RFID-Enabled Sensors on Flexible Low Cost Substrates Type de document : texte imprimé Auteurs : Li Yang, Auteur ; Amin Rida, Auteur ; Manos M. Tentzeris, Auteur Editeur : USA : Morgan & Claypool Publishers Année de publication : 2009 Collection : Synthesis Lectures on RF/Microwaves Importance : 81 p. Présentation : couv. ill.,ill. Format : 23,4 cm. ISBN/ISSN/EAN : 978-1-598-29860-4 Langues : Anglais (eng) Catégories : TELECOMMUNICATION Index. décimale : 28-03 Antennes-radars-sonars Résumé : This book presents a step-by-step discussion of the design and development of radio frequency identification (RFID) and RFID-enabled sensors on flexible low cost substrates for UHF frequency bands. Various examples of fully function building blocks (design and fabrication of antennas, integration with ICs and microcontrollers, power sources, as well as inkjet-printing techniques) demonstrate the revolutionary effect of this approach in low cost RFID and RFID-enabled sensors fields. This approach could be easily extended to other microwave and wireless applications as well. The first chapter describes the basic functionality and the physical and IT-related principles underlying RFID and sensors technology. Chapter two explains in detail inkjet-printing technology providing the characterization of the conductive ink, which consists of nano-silver-particles, while highlighting the importance of this technology as a fast and simple fabrication technique especially on flexible organic substrates such as Liquid Crystal Polymer (LCP) or paper-based substrates. Chapter three demonstrates several compact inkjet-printed UHF RFID antennas using antenna matching techniques to match IC's complex impedance as prototypes to provide the proof of concept of this technology. Chapter four discusses the benefits of using conformal magnetic material as a substrate for miniaturized high-frequency circuit applications. In addition, in Chapter five, the authors also touch up the state-of-the-art area of fully-integrated wireless sensor modules on organic substrates and show the first ever 2D sensor integration with an RFID tag module on paper, as well as the possibility of 3D multilayer paper-based RF/microwave structures.

PSpice for Digital Communications Engineering / Paul Tobin

Public ISBD Titre : PSpice for Digital Communications Engineering Type de document : texte imprimé Auteurs : Paul Tobin, Auteur Editeur : USA : Morgan & Claypool Publishers Année de publication : 2007 Collection : Synthesis Lectures on Digital Circuits and Systems Importance : 199 p. Présentation : couv. ill. en coul., ill. Format : 23,5 cm. ISBN/ISSN/EAN : 978-1-598-29162-9 Langues : Anglais (eng) Catégories : TELECOMMUNICATION Index. décimale : 28-04 Traitement du signal appliqué aux télécommunications Résumé : PSpice for Digital Communications Engineering shows how to simulate digital communication systems and modulation methods using the very powerful Cadence Orcad PSpice version 10.5 suite of software programs. Fourier series and Fourier transform are applied to signals to set the ground work for the modulation techniques introduced in later chapters. Various baseband signals, including duo-binary baseband signaling, are generated and the spectra are examined to detail the unsuitability of these signals for accessing the public switched network. Pulse code modulation and time-division multiplexing circuits are examined and simulated where sampling and quantization noise topics are discussed. We construct a single-channel PCM system from transmission to receiver i.e. end-to-end, and import real speech signals to examine the problems associated with aliasing, sample and hold. Companding is addressed here and we look at the A and mu law characteristics for achieving better signal to quantization noise ratios. Several types of delta modulators are examined and also the concept of time divisionmultiplexing is considered. Multi-level signaling techniques such as QPSK andQAMare analyzed and simulated and 'home-made meters', such as scatter and eye meters, are used to assess the performance of these modulation systems in the presence of noise. The raised-cosine family of filters for shaping data before transmission is examined in depth where bandwidth efficiency and channel capacity is discussed. We plot several graphs in Probe to compare the efficiency of these systems. Direct spread spectrum is the last topic to be examined and simulated to show the advantages of spreading the signal over a wide bandwidth and giving good signal security at the same time.
