Abstract:

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.
