In recent days, electronic devices are very sensitive to harmonics. The harmonic free and high power rating sources are increased to meet the requirement of industries. As conventional two level inverters are not able to provide good quality power, multilevel inverters are becoming more popular due to their ability to generate more output voltage with fewer harmonic. A new multilevel inverter topology with different magnitude of dc voltage sources has been introduced that requires lesser number of circuit components as compared to other topologies for same levels in output voltage. In this topology, minimum switches are required for generation of higher level output voltage. The method is easy to implement and simple. The extended version of this topology generates more number of output voltage levels. Both the operational accuracy and Total Harmonic Distortion (THD) of the output voltage have been evaluated using simulation in MATLAB environment. Asymmetrical multilevel inverters are mostly suited for high power and medium applications. A comparison is done on the basis of THD to check the performance accuracy of different voltage levels of Asymmetrical cascaded H-bridge multilevel inverter. The inverters are simulated and its results are verified through MATLAB/Simulink software.
