Abstract: Solar photovoltaic modules are used to generate electricity from solar energy. The voltage generated during solar PV modules is DC in nature. However, most of the applications require AC quantities as input. Hence, multilevel inverters are employed to convert the DC voltage output of the PV module into AC voltage. In this paper, a detailed study of PV module is presented along with its modeling and simulation results showing the I-V and P-V characteristics obtained at different irradiance levels. The paper also includes the study of cascaded H-bridge inverter topology. Further, a comparative study is carried out between EPWM (Equal pulse width modulation) and SPWM (Sinusoidal pulse width modulation) techniques which enables to select the technique resulting in fewer harmonics for further simulations. The harmonic contents are determined with the help of FFT analysis in MATLAB
