This paper presents details of the experimental implementation of a prototype multi-cellular converter for application in future electricity supply networks. Such a converter is capable of independently controlling power flow between various parts of... Read More about Construction and testing of the 3.3 kV, 300 kVA UNIFLEX-PM prototype.

Feed-forward space vector modulation for single-phase multilevel cascaded converters with any DC voltage ratio (2008)
Journal Article
Leon, J. I., Vazquez, S., Watson, A. J., Franquelo, L. G., Wheeler, P. W., & Carrasco, J. M. (2009). Feed-forward space vector modulation for single-phase multilevel cascaded converters with any DC voltage ratio. IEEE Transactions on Industrial Electronics, 56(2), 315-325. https://doi.org/10.1109/TIE.2008.926777

Modulation techniques for multilevel converters can create distorted output voltages and currents if the dc-link voltages are unbalanced. This situation can be avoided if the instantaneous dc voltage error is not taken into account in the modulation...
