Abstract— The focus of this paper lies on the designing of a sophisticated multilevel single-phase inverter which comprises 21-levels. The proposed configuration makes use of just a single power source and yields a voltage gain up to ten times the input voltage. It is important to mention here that this configuration needs minimum number of switches compared to other multilevel inverter configurations and, therefore, helps minimize the switching loss. As far as capacitors are concerned, they possess a natural capability to balance themselves. Therefore, there is no need for any extra circuit to maintain their balancing in the proposed inverter system. Moreover, NLM technique is employed to generate high quality stepped waveform having low THD. The entire inverter has been simulated in MATLAB/Simulink.
