Predictive Control of a Flying Capacitor Converter [PDF]
2007 American Control Conference, 2007 This paper presents a predictive control strategy for single phase flying capacitor converters. The proposed method allows for the regulation of both the output current and the intermediate flying capacitor voltages, achieving transient dynamics that are superior to those in standard pulse width modulation based strategies.
