Abstract
The modular multilevel converter (MMC) is a promising converter technology for various high-voltage high-power applications. The reason to that is low-distortion output quantities can be achieved with low average switching frequencies per switch and without output filters. Modular multilevel converter pulse width modulation based control approaches are evaluated. The multicarrier PWM techniques such as Phase disposition PWM (PDPWM), Phase opposition disposition PWM (PODPWM), Alternate phase opposition disposition PWM (APODPWM) is employed and a comparative study is done based on the quality of the load voltage and load current output.This paper presents the simulation of single phase modular multilevel converter based on Half-Bridge submodule topology. Simulation has been carried out for various modulation techniques using MATLAB/Simulink and the results are observed
