This paper deals with utilizing the solar energy to feed AC loads. In this paper solar energy will be
converted in to AC by means of Three-level diode clamped inverter in which DC is obtained by means of MPPT
(Maximum power point tracking-Perturb & Observe method). In diode clamped inverter implementation of SPWM
(sinusoidal pulse width modulation) as well as SVPWM (space vector pulse width modulation) techniques for pulse width
modulation and generation of gate pulse to make switches ON and OFF is utilized. After that individual analysis of both
the techniques by doing %THD (total harmonic distortion) analysis is done in which modelling and simulation is done
through MATLAB/simulink .
