This work explores the well-known challenge of achieving voltage balance of capacitors in arbitrary (N-level) flying capacitor multilevel (FCML) converters. In particular, we explore the relationships among measurable circuit waveforms and flying capacitor voltage ‘states’.

Simple direct capacitor voltage balancing of a flying capacitor converter
2005 European Conference on Power Electronics and Applications, 2005This paper proposes a new charge control method for voltage balancing of flying capacitor multilevel converters. Only the signs of the deviations from the nominal capacitor voltages and the sign of the output current are needed to choose proper switching states for charging or discharging the ...

Parallel resonant converter with flying capacitor
2013 IEEE International Conference of IEEE Region 10 (TENCON 2013), 2013This paper presents a parallel resonant converter for high input voltage applications. In order to reduce the voltage stress of active switches, two half-bridge converters are connected in series at high voltage side. Flying capacitor is adopted between two series half-bridge converters to automatically balance two input capacitor voltages.

A Flying-capacitor Modular Multilevel Converter
2018 IEEE 7th International Conference on Power and Energy (PECon), 2018With the increase of HVDC transmission, HVDC grids are the inevitable trend of the future. HVDC DC-DC converters act as the indispensable components to transmit energy and connect HVDC grids with different voltage levels. This paper proposes a flying-capacitor modular multilevel DC-DC converter for HVDC grid connection and offshore wind farm collection
