Abstract: The main objective of this paper is to propose a new single phase asymmetrical type multilevel inverter with minimum number of switches. The proposed multilevel inverter consists of level creator unit which generate only positive levels of outputs. The H-bridge inverter is added to change the polarity of the output voltage. The comparison between the proposed topology with existing inverter topologies is presented. The proposed inverter consist of six voltage sources, 11 main switches and 4 H-bridge inverter switches. Different algorithms are used to calculate the switching angles and the results are compared with the reference. The proposed inverter produces output voltage waveform with minimum THD as compared with the reference. The computer based simulation model is developed using MATLAB/SIMULINK software to verify the function of the proposed inverter.
