IET Power Electronics, 2015 In this study, a novel developed structure of a converter based on double flying capacitor multi‐cell named progressive double flying capacitor multicell (PDFCM) is proposed. The main advantage of this proposed structure compared with DFCM converter is generation of more output voltage levels while having the same number of devices.

Initial Capacitor Charging in Grid-Connected Flying Capacitor Multilevel Converters
IEEE Transactions on Power Electronics, 2014 This letter reports a method for the initial charging of capacitors in grid-connected flying capacitor (FC) multilevel converters. A resistor is inserted between each phase of the FC converter and the grid. A voltage balancing algorithm is activated from the beginning of the process and the FC converter generates proper output voltages to achieve ...
