A New Simplified Approach for Capacitor Voltage Balancing of Flying Capacitor Multilevel Converters Using Space Vector Modulation

This paper presents a new, simple and generalized approach to calculate flying capacitor currents for an n-level flying capacitor converter without the use of look-up tables. The performance of the proposed method has been studied for a three-, four- and five-level flying capacitor converter in MATLAB/Simulink environment.
