By Janos Hamar, Hirohito Funato, Satoshi Ogasawara, Octavian Dranga [View]
[Download]

Abstract: The main objective of the paper is to present new browser-based, interactive software tools for modeling of various power electronics circuits. The static and dynamic operation, including the continuous and discrete time linearization of widely applied dc-dc converter cells are discussed in the first part of the paper. The second part focuses on the basics of the pulse-width-modulation and its application in one-phase sinusoidal inverters. The interactive tools provide numerous excellent opportunities for industrial and academic education. Another application field of numerous embedded interactive software components is their utilization as fast, real-time modelbuilding tools.

[Download]

Abstract: Virtual laboratories can become important components of the teaching process, because using them several experiment-oriented problems can be solved easily and also from the distance. Graduates using virtual laboratories will be better trained when they enter the job market. In the paper a laboratory work will be presented having two components: a simulation and an experimental module. Both can be used for the preparation of a real lab and for accessing the real-world experiments. The virtual lab modules can also allow multiple students to remote access the experiments, the multicast data transfer mechanisms and arbitration mechanisms.

   Interactive Simulations of Power Electronics Converters
By Jean-Jacques Huselstein, Philippe Enrici, Thierry Martire [View]
[Download]

Abstract: This paper presents interactive "apparent real time" simulation applications for the teaching of powers electronics. We present a study of of the following converters : buck converter, one, two and four quadrant chopper, boost converter, single-phase inverter, Flyback converter, rectifier on capacitive load, ... The following simulations VI (LabVIEW Virtual Instrument) could be useful for power electronics converter sizing. However they are mainly intended for teaching purposes. The aim of this work is to show on a computer screen (or a classroom screen with a video projector) simulation that’s looks like what could be seen on an oscilloscope screen with a real circuit. Compared to a traditional circuit simulator, the interest is to be able to modify any parameter or component value and to visualize the produced effect immediately? without starting a new simulation. In a course the professor can show the principle of the powers electronics converters much easier and more interesting than with a succession of traditional slides. The students can then continue the study of these topologies in the computer room or at home. These applications being put are left at their disposal on an internet site.

   MATLAB Web Server and M-File Application
By Suzana Uran, Karel Jezernik [View]
[Download]

Abstract: Using of MATLAB Web Server(MWS) is attractive for students as well as for universities due to reduction of costs for both parties. Standard MWS applications support structured hands-on experiments welcomed for visualization of hard to grasp concepts and as a design tool. MWS applications for Math, Power electronics and Control design, part of a virtual laboratory created at University of Maribor, are represented. In addition a M-file MWS application - an example of unstructured MWS environment allowing students to write the MATLAB M-files of their own and to execute them on MWS is presented in detail. Only a simple text editor and an Internet browser are needed by a student to use M-file MWS application.

   Use of Free/Open Source Software in e-Education
By Martin Terbuc [View]
[Download]

Abstract: We are in the age of computer and internet but most of teaching is still performed in classical way. We speak a lot about new method of teaching and e-learning, which are connected with large investment. The expense for software we can reduce with use of free/open source software. That we don't use it often is because we don't know it and we fear from new things where we need to put some effort. In this paper free/open source software and movements in the world will be presented. The benefits of using this software from primary school to university will be shown.
