Abstract :
This paper provides a mathematical model for voltage natural balancing process in three phase capacitor-clamped multicell converters. The analysis leads to state-space model of the converters. State-space representation of converter can be utilized to investigate the start-up and steady states of internal flying capacitors voltages. To provide verification, numerical solutions for three phase capacitor-clamped multicell converter´s analytic model are presented.
