Abstract

In recent years, the multilevel converters have been given more attention due to their modularity, reliability, failure managementand multi stepped output waveform with less total harmonic distortion. This paper presents a novel symmetric multilevel invertertopology with reduced switching components to generate a high quality stepped sinusoidal voltage waveform. The series and parallelcombinations of switches in the proposed topology reduce the total number of conducting switches in each level of output voltages. In addition, a comparison between the proposed topology with another topology from the literature is presented. To verify theproposed topology, the computer based simulation model is developed using MATLAB/Simulink and experimentally with aprototype model results are then compared.
