LABORATORY POWER CONVERTER – ANALYSIS AND MODELLING FOR STUDENT TRAINING

The laboratory facilities of the faculty play an important role in training future maritime electrical engineers. With the electrification of the marine industry, the importance of understanding electrical laboratory equipment is increasing. Technological advances will expose future maritime electrical engineers to increasingly complex systems, circuits, and topologies. In this paper, the focus is on a widely used component, the self-commutated power converter. The aim of the paper is to familiarize the students with the topology of the converter used in the laboratory exercises. The used converter is built on black-box principle i.e., the students cannot see the discrete components. The schematic that can be seen on the converter itself represents the mains filter and the dU/dt filter on blackbox principle, i.e. the manufacturer does not provide any technical details about the filters. The model of the converter with mains and dU/dt filters is created using Matlab/Simulink Simscape components. To validate the model, the voltage and current waveforms measured on the actual device using an oscilloscope and the original manufacturer's software are compared with the simulated output waveforms.
