Flying-capacitor boost converter

2012 Twenty-Seventh Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2012
This paper introduces the flying-capacitor dc-dc boost converter. In the proposed topology, a high voltage gain ratio and improved conversion efficiency are achieved with low inductor core and copper losses. The input current ripple of the new converter is low while its ripple frequency is high, yielding a low-sized input filter.

New flying capacitor multilevel converter

2011 IEEE International Symposium on Industrial Electronics, 2011
This paper proposes an improved version of conventional flying capacitor multilevel converter known as active flying capacitor converter. The proposed converter replaces the clamping capacitor of the three-level flying capacitor converter by number of series connected half or full bridge cells, and uses these active cells to generate multilevel voltage
