This work intends to introduce the use of remote laboratories for power electronics teaching, by means of VISIR (Virtual Instrument System in Reality). The system is applied for the analysis of two simple circuits, a RC filter and an AC measuring network. The proposed methodology introduces remote activities after theoretical lessons, pen and pencil exercises, circuit simulations, and on-site laboratory experimentation. This strategy has been validated by professors and a pilot group of students at the Electronics Department of the Federal Institute of Santa Catarina. As a general conclusion, remote labs contribute to learning, but cannot substitute completely on-site laboratories.
Virtual Power Electronics Labs for Online Teaching
2020 55th International Universities Power Engineering Conference (UPEC)
A textbook and traditional classroom only approach in teaching power electronics can mean that design of power electronic circuits could be isolated and will be difficult to absorb by students. If we add to this, the sudden switch to virtual delivery of lectures then the challenge to engage the students in the learning process of power electronics could be even more complicated. In this paper, a virtual way of teaching power electronic circuits without much compromise with real practical environment is presented. A boost and flyback converter circuits are presented as a case study where all practical parameters are considered in the 'virtual' practical circuit.
Simulation Tools for Power Electronics Courses Based on Java Technologies
2010
This paper presents interactive power electronics educational tools. These interactive tools make use of the benefits of Java language to provide a dynamic and interactive approach to simulating steady-state ideal rectifiers (uncontrolled and controlled; single-phase and three-phase). Additionally, this paper discusses the development and use of Java applet programs to assist the teaching of conventional power electronics rectifier circuits and to serve as a first design tool for basic laboratory experiments in power electronics courses. Comparison was made among results obtained using a well-known simulator package, experimental results, and the developed interactive simulation applets in order to validate the latter.
Development and implementation of a virtual laboratory for fundamentals on power systems
2014 International Conference on Optimization of Electrical and Electronic Equipment (OPTIM), 2014
In almost any engineering department, a laboratory is an integral part of the educational process. The laboratory is a key component in the field of engineering in general, and electrical power engineering in particular. The virtual laboratory (VL) is a simulated experiment run by students on a computer station program; it can transform the conventional laboratory experiments into an interactive virtual environment, allowing simple and complex phenomena to be investigated by students just by changing the parameters and conditions of the experiments. This paper describes the development and the implementation of a VL, named VLABPOWER, for fundamentals on power systems. Mainly, electrical power engineering students will using to increase their understanding and to bridge the gap that exists between the theoretical part in the class and the practical at the traditional (real) laboratory and to better prepare before going to the traditional laboratory. The purpose of this work is to develop and implement a VL in order to enable students to have a better understanding of the experiments done in the traditional laboratory and to familiarize themselves with the different components used for those experiments. It presents a virtual interactive experiment environment that simulates the physical conditions on the transmission line. Moreover, it discusses and explains different types of short circuit faults such as symmetrical and unsymmetrical faults, modeling of different type of lines, and load condition analysis. I.
An Integrated Laboratory for Teaching Electrical Engineering
IFAC Proceedings Volumes, 1995
The modem tendency towards interdisciplinary work, the increasing demand on laboratory classes in Electrical Engineering courses and the necessity to overcome the limited financial support for education have been solved with the expanded use of a Power Electronics Teaching laboratory at UFRJ. This paper describes the equipment hardware/software and exemplifies the teaching process. 1. INIRODUCTION The following paper describes the use of a Power Electronics Laboratory (Rolim, et al., 1993) as an integrated teaching laboratory for: Power Electronics Electric Circuits Electric Machines Electronics Real Time Processing Signal Processing Control Theory and Simulation. The proposed approach has been motivated by an increasing demand on laboratory classes in the Electrical Engineering Course at UFRJ, by a new trend for interdisciplinary work and also as an effort to overcome the limited financial support for education. The equipment was primarily intended for teaching basic principles of eletronic power converters and their applications (see Rolim, et al. , 1993). The equipment heart is based on a rack, schematically shown in top view in Fig. 1. The layout of the power bus rails and connectors on the rack reproduces the visual appearance of the switching matrix idealized by Wood (1981). Each switch module comprises a power semicondutor switching device and its driver circuit.

This paper proposes a new computerized educational approach to teach the power electronics laboratory. It describes PSpice implementation of the core power electronic circuits that depend on thyristor circuits to identify behaviors with load variations. It uses the developed simulation models to support and enhance power electronics education at the undergraduate level. These simulations successfully integrate the contents of the power electronic laboratory course. A study of the impact of these simulations on the results of the students showed that it helped them to master the course contents and to gain better grades.
Design and implementation of an electronics laboratory simulator
IEEE Transactions on Education, 1996
This paper describes the design and implementation of a computer-simulated laboratory for use in undergraduate engineering education. The simulated laboratory is implemented in a windows environment. Several forms of tutorials and other assistance are available to the user to complete the laboratory. Evaluations indicate that when the simulation is used with class lectures, there is a significant improvement in both theory and lab knowledge. Use of the simulation significantly cuts subsequent time and requests for assistance in the physical lab.

The article presents a review of current e-pedagogical methods of designing study programs for education in the field of electric and computers engineering. Experimental engineering skills and abilities can be developed by using remote labs and simulations. The development of critical thinking of engineer students takes place while students work with virtual resources, and students need to understand what kind of results they get for each experiment. Even if it addresses the same problems by differentiating the simulation laboratories - it focuses on another field: not the ability to do this, but how you can do it. Online laboratories are also fundamental to the experiments the student performs in the individual study because they are specially designed for distance students who need to gain an introductory knowledge and familiarity with real-life phenomena. These on-line experiments can be carried out in various engineering fields, including Electrical and Computer Engineering. The instructional design model is based on the ADDIE model, which includes the phases of analysis, design, development, implementation, and evaluation. Virtual Learning Environments (VLEs) are used to make online interactions between Students and Teachers. Moodle (Modular Object-Oriented Dynamic Learning Environment) is known as an online course management system (CMS). Learning Process and Content Management Systems (LCMS), in this case, Moodle (an open source so
