In transformation of resources like power the multilevel inverters are the best technology. Output as stair waveform signal feed as input to many of the DC sources. The description of multilevel inverter topology is described in the paper. The presentation consist of 7 level architecture principle and to obtain best quality of output signal the algorithm of adaptive genetic is adopted to slow down the harmonic content. In actual time the evaluations of appropriate switching angle used to analyse the THD minimization. The overall observations are declined based on 7 level to cases in other levels and THD determination in various states. These studies are based on MATLAB simulation and programming. The proposed work is simulated using MATLAB software which gives the model accuracy rate of 80% with the lesser error rate. The multilevel inverter designed using the proposed method removes the harmonic function at various input voltage with the minimum loss factors.
