This book was released on 2005-11-04 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: (Dissertation is written in Spanish.) Using PSpice of MiscroSim to simulate power converters sometimes brings awkward complications such as the simulation of real magnetic components. It deals a little bit of work to bring a good agreement between experimental and simulated results. Simulation with linear inductors or transformers does not produce good results. The reason is that real magnetic components present saturation and hysteresis, a phenomenon that characterises magnetic materials. The hysteresis or B-H loop of a magnetic component is highly dependent on frequency, waveform (not very important for ferrite material), temperature, excitation level, etc. Although PSpice includes in its magnetic library a list of non-linear components, rarely these parameters are coincident with our working conditions or simply they are not specified. In all of these cases it is necessary the modelling of non-linear magnetic cores for each particular application. Here we present a systematic procedure to obtain real PSpice parameters to model magnetic materials using the Jiles & Atherton theory. The procedure is totally general and models the static B-H loop given by any manufacturer as well as the one that can be obtained in accordance with some specific working conditions. This is really important, since it helps the designer in obtaining model parameters for any high frequency applications, which are not correctly presented in PSpice libraries. The modelled magnetic material is used for power electronics circuit simulation, which uses magnetic materials, working at frequencies in the region of kH, to construct transformers and inductors. Magnetic materials are the most critical components in electronics simulators due to their non-linear behaviour. This work examines the modelling of the magnetic core hysteresis for high-frequency applications. As example of application, a buck converter with their inductor working near saturation is implemented and their experimental waveforms are compared with the simulated ones obtained with this model. With this procedure a good concordance between experimental and simulated B-H loop is obtained and the simulation of the power converter is reached properly.

Book Synopsis Dam Maintenance and Rehabilitation by : J.A. Llanos
Download or read book Dam Maintenance and Rehabilitation written by J.A. Llanos and published by CRC Press. This book was released on 2002-01-01 with total page 1012 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the life of a dam, changes in safety standards, legislation and land use will inevitably occur, and functional deterioration may also appear. To meet these challenges, these Proceedings from a panel of international experts assess, define and re-evaluate the design criteria for the construction of dams and the many attendant issues in on-going maintenance and management. Authors include international specialists: academics, professionals and those in local government, utilities and suppliers. Practitioners from these same fields will find the book a useful tool in acquiring a comprehensive knowledge of managing and retrofitting dams, so that they can continue to meet society's needs.

This book was released on 2013-04-29 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: The predominant view in economic theory until the crisis of the '70s, argued the great enterprise was the key player in the innovation process, this was conceived as an activity that unfolded in specific areas, with clear responsibilities and predetermined objectives. This operating structure of the innovative process was functional demand model that favored the standardization of production. The innovative process was developed predominantly by firms that had a domain oligopolistic market from which they made windfall with which financed the research and development activities. In this context, the role of SMEs in the innovation process is limited to covering the portion of the market that big companies left.
