Recently, multilevel converters have received the largest amount of attention because of some advantages such as high quality output waveform, lower harmonic distortion and reduced electromagnetic interference. A novel cascaded multilevel inverter topology is proposed in this study. First basic part of inverter configuration is described and then symmetric and asymmetric form of converter is discussed. Comparison study is done between the proposed topology and cascaded H-Bridge (CHB) converter. Number of components such as switch number and gate driver has been reduced in the suggested topology compared to multilevel CHB converter. Furthermore, Peak inverse voltage of suggested topology is lower than that of conventional CHB converter. Reduction in number of on-state switches in introduced topology leads to the reduction of power loss and voltage drop. Moreover, modularity is other characteristic of this configuration. Finally, simulation and experimental results are presented. The presented results show the validity and the effectiveness of the proposed multilevel structure.
