A new cascaded multilevel converter topology with reduced number of components

In this paper a new modular multilevel converter topology is proposed. One basic module for the proposed topology is established. To produce output voltages of both the polarity one H-bridge is used at the output. This topology suggestively reduces amount of power electronics components, dc voltage sources and driver circuits used. Here algorithm for both symmetric and asymmetric source configuration is shown. Comparison of the proposed topology with conformist and some new topologies are also presented here. The recital and purposeful correctness of the proposed topology are confirmed by simulation of a 15-level multilevel inverter based on the proposed topology using MATLAB/SIMULINK.
