This thesis presents new topologies for multilevel converters based on flying capacitor multicell (FCM) structure. The proposed quadruple FCM converter has a modular multicell structure which can be easily extended to increase the number of output voltage levels. Multilevel converters with one dc voltage source are attractive in many applications as they do not need rather expensive and bulky multi-winding input transformer connection at the dc side. On the other hand, not all align=left Key Words capacitor voltage balancing, flying capacitor multicell converter, hybrid topology, phase shifted carrier pulse width modulation, multilevel converter, space vector modulation.
