In this workshop, attendees will get initial insights in the PLECs power electronics simulation tool for modelling and simulating power electronics converters. Furthermore, knowledge on analysis and simulation from lecture 1 will be extended AC/DC multi-phase systems including also state-of-the-art three-phase power electronic circuits for renewable energy systems. Also, single phase AC/DC inverters for PV-applications will be discussed. Moreover, input and output filter design issues will be addressed. Again, participants get the chance to practice their skills and can work on selected design examples (AC/DC).
