   High-Frequency Pulse Width Modulation for Power Converters
By J.-C. Le Claire; R. Moreaú [View]
[Download]

Abstract: The delta modulation technique permits an accurate tracking of an arbitrary reference. Spectrum of the current going through an inductive load shows a very low THD. Moreover, notches are located around the sample frequency multiples, which is of interest for converters without output low-pass filter. In this paper, we demonstrate that the delta modulator structure can be easily implemented when regulating the converter output current going through an inductive load. Then, we propose a mean for computing the load current spectrum using the Laplace and Fourier transforms.

   Multilingual Web-based Teaching and Learning techniques for Power Electronics
By Y. Lu; K. W. E. Cheng [View]
[Download]

Abstract: Online learning is now under rapid development as a result of the multimedia and Internet development. Teaching and Learning can be now based on Internet. It comes to a question that how we can make users learn web-based material or lecture easily. Although many web sites provide web-learning package, they all are purely changing the materials from paper copy into soft copy in html form with some animation to enhance the learning interest. Besides that, there is no anything special. In Far-East, the mother tongue is not English which may impose some difficulty for them to study engineering because a lot of literature are written in English. This is especially for power electronics which is an emerging technology and many documents, technical papers and books are written in English. However, a proper Web-based teaching and learning package should consist more function than that. A Web-based teaching and learning package is developed especially for Power Electronics course. This package aims not only to present the material in the web, but also provide a number of features to enhance learning capability. It includes advanced translation and language tool namely browser enhancement system (BES). Actually the BES is a plug-in program written under Internet Explorer (IE) environment. The main function is to translate a text and to give explanation of selected text under the IE. Also the BES program can change a text presentation into speech presentation. The main difference between BES and the conventional approach for text translation is selecting a text under the IE instead of inputting a text into a text field by users. This innovative method of the translation can also be used anywhere in the world. The package also includes some other features including interactive exercise tool. The package has been very well received by both lecturers and students.

Abstract: Now a days, there are new accelerating factors of a country’s society and economy. The New Society of Information and Knowledge and the New Society of Learning. The economy globalisation and the high-speed technological innovations are demanding more and more efforts in formation, training and professional recycling. The growing importance of the energy sector and, in particular the electric energy sector one in economy of a country, gives this sector a higher importance. The energy management subject assumes in this context a very special relevance that should follow and study the evolution caused by the opening of the energy sector to the private investment, with special incident to the end of regulation and to privatisation of the electric energy sector, not forgetting also the role of the advanced technologies of production on the integrated management of energy in industrial installations, in the service companies and in our homes. This work wants to conceive a set of multimedia tools in order to make the energy management subject available though the services given by the Internet and appointed to support the self-learning of those who have interests in the energy management.

   The Interdependence of Education and the Future of Alternative Energy
By A. Tuckey; J. J. Nelson [View]
[Download]

Abstract: Global energy demands are increasing while the number of students interested in power engineering is decreasing. The introduction of alternative energy education stimulates new students’ interest in the field and heightens concerns for the environment and future energy supply. Student competitions in alternative energy create publicity and attract students while presenting a real-world engineering problem. Improving consumer alternative energy education will promote an increase in sales in the alternative energy industry, causing an increase in demand for alternative energy educated engineers. The focus of this paper is not on the advantages or disadvantages of alternative energy as a technology, but rather on the role it plays within education and the role education plays within alternative energy. A recent look at student power engineering trends involving an NSF funded center is presented. Power engineering undergraduate student enrollment data is shown for a university over the past ten years. The foundation of this paper suggests the importance of student competitions in gaining momentum for both student participation and community approval regarding alternative energy. The paper specifically details a student competition involving fourteen U.S. higher learning institutions on a common goal of lowering the costs associated with power electronics in domestic alternative energy supplied from fuel cells. Additionally, other related educational opportunities are discussed.

   Theory of Electrical Machines for Power Electronics and Electrical Drives Applications — Didactic Approach
By M. Ronkowski [View]
[Download]

Abstract: A new approach to teaching the theory of rotating electrical machines (EM) is presented. The main idea of the approach is based on the following assumptions: individual types of EMs are distinguished only by the control method of the machine fields position in space; in EM the two fundamental couplings can be distinguished — ideal transformer coupling and ideal electromechanical coupling. Using the circuit models (lumped parameter models) of the couplings as „building blocs” the multi-ports models of basic rotating EMs can be easy developed for study the power conversion systems. As an example the induction motor model has been developed for the analysis of drive system with power electronic converter supply.
