Modelling and simulation of 1 KW solar generation system to grid connected with use SPWM & SVPWM.
This paper present solar photovoltaic (PV) generation system to gird-connected with low harmonic distortion in the output voltage. Solar generation system utilizes maximum power point tracking is achieved with perturb and absorb (P&O) Method. In three level diode clamped inverter implementation of sinusoidal pulse width modulation (SPWM) as well as Space vector pulse width modulation (SVPWM) techniques for pulse width modulation and generation of gate pulse. In this paper first a model for SPWM is made and simulated using MATLAB/SIMULINK software and its performance is compared with SVPWM. The simulation study reveals that SVPWM voltage more effectively and generates less Total harmonic distortion (%THD) when compared with SPWM.
