Another project completed as part of my MSEE degree, this time for the course in Power Electronics. Our professor, Dr. Greg Mowry of the University of St. Thomas, allowed each of us to choose a published power electronics paper and then verify its results, including simulating any topologies. It was interesting to see what my classmates came up with during presentations on the last day. One pair actually found enough errors in their selected paper to disprove it!
I found a paper which presented a novel topology for a single-phase multilevel inverter that is scalable for photo-voltaic (PV) arrays. The authors were a bit opaque regarding how they controlled the thing for grid connection, so I couldn’t verify everything. But I did have a good time simulating the topology in PSIM.
Here is my report and presentation:
