Remote experiment system and internet based teaching of PWM techniques for three-phase voltage source converters

The paper details a successful of a remote laboratory and Internet based teaching of PWM techniques for three-phase voltage source converters. The first stage of exercises is based on developed Java applets for interactive simulation of carrier based PWM (CB-PWM) and space vector based modulation (SVM) techniques. The physical experiment is based on a three-phase IGBT bridge converter with DSP control and modulation. Signal measurements and processing are implemented in LabView environment. The master control and experiment Web pages are governed by Moodle course management system, which provides access restrictions by means of a booking system. The presented PWM module is a part of power electronics and drives course developed within the project EDIPE supported by European Commission - Leonardo da Vinci II Programme.
