Capacitors Natural Voltage Balancing Mechanism Investigation in Flying Capacitor Multicell Converters

This paper presents an analytical analysis of capacitors voltage balancing process in flying capacitor multicell converters. The analysis leads to modeling and state-space representation of converters. State-space representation of converter can be utilized to investigate the transient and steady states of internal flying capacitors voltages. To provide verification, numerical solutions for time-domain differential equations of converter state-space representation are compared against simulation results.
