Abstract

This paper proposes an innovative active voltage control technique for flying-capacitor (FC) multilevel converters. The proposed active control method on the basis of the logic-equations exploits converter's measured variables including the capacitor voltages and output current to generate a switching state that regulates the FC voltages at reference values and also produces the commanded PWM voltage-level. Simulation results and experimental measurements are provided to confirm the introduced method and derived equations.
