Abstract :
This paper presents analysis of the effect of modulation strategy on the modular multilevel converter including sub-module capacitor size calculation, capacitor ripple and capacitor balancing strategy. Simulation and experimental results validate the analysis presented and some features such as effective switching frequency per device and current and voltage stress on each device compared to other methods, are addressed.
