   E-Learning Tool For Ac/dc Converters
By J. Marcos, C. Quintans, J. Doval, R. Costas, A. Nogueiras [View]
[Download]

Abstract: This work presents a tool for learning the operation of AC-DC converters. The software developed allows the visualization of voltages and currents in the converter under different load conditions and trigger angles. At the same time shows what are the devices in ON and OFF state. Several topologies of AC/DC converters can be studied by using this tool.

   E-Learning Tool For DC/AC Converters
By J. Marcos, C. Quintans, J. Doval, O. Hidalgo, A. Nogueiras [View]
[Download]

Abstract: This paper presents a software application for making easy the learning of the DC/AC converters operation mode. By means of animation, the current paths and the devices in the ON state can be observed for each time interval. The user can change the values for the load and for the modulation index. Some additional information is included for the student, as the basic concepts of the converter in pdf format, links to web pages with information of inverters and power electronics devices.

   Experimental Teaching Of Switching Modes For Single Phase Inverters
By Andreas Schmidhofer, Andreas Schmid, Helmut Weiss [View]
[Download]

Abstract: The standard voltage for batteries used in e.g. mobile applications is 12V. To extract the stored energy for common AC 230V loads a single phase inverter has to be connected. Single phase inverters are not only used in typical power electronics applications it is widely used for power supply in the everyday life. For the teaching of such systems, simulation tools are very convenient, but universal experimental arrangements give a better understanding for students due to practical point of view. In this paper a common single phase inverter system is applied to investigate different switching modes (square wave, harmonic elimination, PWM) and to see the effects of harmonic distortion of the output voltage. For this purpose the used rapid prototype system dSPACE is used for the comfortable control and switch parameter changing.

   Formula Interpretation And Simulation With Interactive Parameter Change In Field Of Power Electronics
By Eberhard Brenner [View]
[Download]

Abstract: The contribution presents the possibilities of Lab- VIEW in the special application as formula interpreter by using of the formula node. The main advantage is the immediate presentation of results in case of a parameter change. The presentation of the time behaviour, the calculation of characteristic values and curves for typical examples of power electronics and control engineering are shown. Further some features of the simulation program LEDSIM with an integrated on-line parameter change will be presented.

   Teaching Dc-Dc Switch-Mode Converter Design To Undergraduates In Power Electronics Education
By Alberto Landi [View]
[Download]

Abstract: This paper presents an outline of an integrated lecture-laboratory lesson for undergraduates in power electronics. In a new university structure, where the number of hours per course is being reduced, productivity of learning must increase, in order to avoid a decrease in the quality of education. As a consequence, teachers should make every effort to present their subjects in the most interesting and appealing way possible, so as to accelerate the learning process. The example proposed consists in a typical subject for power electronic courses: DC-DC switch-mode converters. Theoretical concepts are presented in a lecture suitable for the level of the students. Since the objective is to obtain rapid and easy learning, attract the students’ attention and stimulate their interests, the lecture integrates extensive use of laboratory activities. The case of designing a multifunctional converter is briefly described, as an example of laboratory work.This paper presents an outline of an integrated lecture-laboratory lesson for undergraduates in power electronics.

   Teaching Of Power Electronics. From Graphic Representation To Animation
By B. Davat(fr), P. Bauer(nl) And P. Van Duijsen(nl) [View]
[Download]

Abstract: The proposed paper presents the evolution of teaching of Power Electronics since the 70s when appears the first automatic program of simulation of static converters to the actual development of interactive animations. Different methods of visualization and graphic representation of converter operation are surveyed and possible ways of interactive animation are introduced.

   Topical Problems Of Teaching Of Electrical Drives
By L. Liivik, R. Jansikene, T. Lehtla [View]
[Download]

Abstract: Fundamental problem of teaching today is the contradiction between are a large quantity of new information on the one hand and limited duration of training course on the other hand. For the decision of this problems it is necessary to search for new methods of teaching. The structure of grading system and a course of electrical drives are described. Important teaching problems, such as selection of laboratory equipment, integration level of theory and practice, e-learning, simulation and modeling methods are discussed.

   Transient Processes Of Ac Machines (50 Years Of Hungarian, 45 Years Of German And 40 Years Of Russian Editions )
By Sandor Halasz, Istvan Vajda [View]
[Download]

Abstract: The paper is dedicated to the 50th anniversary of the first publication of the world-wide well known book of Professors of Technical University of Budapest: K. P. Kovács and I. Rácz that opened the new epoch in the theory of ac machines and especially in the investigation of transient phenomena of induction motors. In the present time the space vector theory – in many respects due to this book – became a usual and widespread method in investigations of ac machines and in controlled semiconductor ac drives.
