Abstract: In micro grid system, the distributed renewable energy source (DRES) establishes the continuity of supply by using DC-AC inverter topology. Due to various disadvantages classical DC-AC inverter topology is unsuitable for grid connected DRES, in stage various multilevel inverter designs came into presence. The cascade H-bridge based multilevel inverter plays a significant role in many applications and applicable to medium-voltage by utilizing certain standard limitations. This peculiar design achieves high quality output voltage and current waveform as staircase waveform. The objective of this paper is to obtain higher output voltage level with less number of switches, less cost and lower THD values. It is carried out by asymmetric multi-cell CMLI topology. Hence this paper is introducing a proposed 85 level asymmetric multi-cell cascade multilevel inverter. It improves the fundamental component and also reduces the THD value by using less number of switches while comparing to other topologies of CMLI. In order to verify the proposed topology is integrated to micro-grid by using MATLAB/SIMULINK software and the results are conferred.
