Renewable energy sources play an essential role to meet the future energy demands in both rural and urban locations. Because of growing awareness of negative impact of fossil-fuel on the environment, it is very necessary to integrate renewable energy into the power grid to improve dependability and power generating quality. Solar energy is getting the most scientific interest of all non-conventional energy resources. Photovoltaic (PV) cells are used to convert the Solar energy into electrical energy. There is no emission of harmful greenhouse gas thus it’s environmentally friendly. Solar (PV) system produces DC voltages, so to get AC power there is a need of power converters. A multilevel inverter can create a defined output voltage from several DC voltage levels at its input, whereas traditional PE converters can only flip between two voltage levels. The main problem with these power inverters is that they contain harmonics which affects the power quality. To overcome this problem different multilevel inverters and modulation techniques are adopted to get smooth AC waveform. An Asymmetric double H bridge MLI model is simulated in MATLAB/SIMULINK software. The proposed MLI is generating a 15-level output by feeding PV panel output in input side. To trigger the switches, multicarrier PWM technique is used and THD calculation is done by FFT analysis tool which is 8.16%. For getting maximum PV output, MPPT perturb and observe algorithm is employed.
