Improved natural balancing with modified phase shifted PWM for single-leg five-level flying-capacitor converters [PDF]

, 2012
Flying capacitor converters (FCCs), as most multilevel converter topologies, require a balancing mechanism of the capacitor voltages. FCCs have the valuable property of natural voltage balancing when a special modulation technique is used.
