Capacitor Voltage Balancing of Flying Capacitor Multilevel Converters by Space Vector PWM
IEEE Transactions on Power Delivery, 2012Proper operation of a multilevel flying capacitor converter (FCC) necessitates a closed-loop voltage balancing strategy. This paper proposes a space vector modulation (SVM)-based approach that benefits from the switching state redundancy of an n-level FCC to implicitly carry out the voltage balancing task within the switching strategy.

Capacitor voltage balancing in full binary combination schema flying capacitor multilevel inverters
IEEE Power Electronics Letters, 2003Recently, the full binary combination schema (FBCS) method has been introduced to control the flying capacitor multilevel inverter. This method has the primary advantage that the number of voltage levels can be increased for a given number of semiconductor devices when compared to the conventional control methods.
