DESIGN OF POWER ELECTRONIC SYSTEM WITH VARIABLE TOPOLOGY OF THE MAIN CIRCUIT FOR EDUCATIONAL SUPPORT OF LABORATORY EXERCISES OF POWER SEMICONDUCTOR CONVERTERS

Abstract

Power electronics emerges more and more within daily life. Its use is widely increased within many application areas, at the same time, industries are emerging in which this technology is being involved for the first time ever. Regarding this trend, there is need for qualified and experienced people with the knowledge of the power electronic systems. This contribution presents the way how to support educational process of the power electronics, while the focus is given here on the experimental-laboratory training. We have developed a unique power electronic system experimental board, which is equipped with necessary electronic components to be able to form standard and advanced topologies of power semiconductor converters. The students can understand operational principles of power rectifiers, DC/DC switched regulators, isolated DC/DC converters, while open loop and closed loop operation can be studied as well. Final paper will contribute with key construction aspects, main circuit components and circuit topologies with their operational principles and examples from measurements. The paper should inspire more university professionals working in this field, i.e. it supports the idea how to increase the practical way of the university study in the field of electrical engineering.
