Abstract :
Multimodular systems based on the multilevel flying capacitor (FC) converter topology are discussed in this paper. Three control techniques are studied and their performance is compared against specific criteria. Different types of multicarrier sinusoidal PWM (MSPWM) techniques used for each module along with the phase-shifting (PS) concept among the different modules are considered. Techniques with high frequency modulation ratio and the fundamental frequency PWM (FFPWM) are studied. The total harmonic distortion (THD) of the output quantities, the system´s bandwidth, and the potential switching losses are discussed. Simulation results are given to support the findings.
