Abstract: There are numerous constraints in removing power from renewable vitality assets. To minimize the power shortage and to fulfill the power demand, power removing strategies must be progressed. Multilevel inverter is utilized to concentrate power from solar cells. The Cascaded H-Bridge (CHB) converter is one of the prominent sorts of Multi Level Inverter (MLI) as a result of its particular structure and high quantities of repetitive switching states. Harmonics in multilevel are because of shameful determination of switching angles to the entryways of the inverter switches. Nearness of harmonics prompts unintentional stumbling of transfers and inaccurate estimation of voltage and current by transformers. The proposed work manages particular selective harmonic elimination using fuzzy logic control to generate switching angle for the eleven levels cascaded h bridge controlled by five variable dc sources. The modulating switching angles are upgraded at every cycle of the yield crucial voltage. Results are checked utilizing MATLAB/SIMULINK environment.
