Renewable energy sources are a viable solution to tackle the growing supply and demand gap. They are being favored worldwide for power applications due to their cleanliness and sustainability. Solar energy is considered to be the most abundant renewable energy resource. The solar photovoltaic technology is being adopted for both distributed as well as centralized generation. The output from renewable sources is in DC, it requires conversion to AC for grid integration and large scale utilization. This conversion is carried out using inverters. Traditional inverters introduced issues like high switching losses, harmonic distortion, and poor-quality output. Multilevel inverters are advanced form of conventional inverters and possess much higher efficiency. In this paper, MATLAB/SIMULINK software is used to model a CHB sub-MLI. The PV panel output is fed to CHB sub-MLI to generate a 15-level AC voltage. The switches are triggered using multicarrier phase opposition disposition PWM. FFT analysis tool is used to calculate the THD which is obtained as 3.11 %. MPPT perturb and observe algorithm is employed to guarantee maximum PV output. Consequently, 15-level AC output is generated and fed to the load.
