This research proposes grid synchronisation with PV through a sliding-mode controller. P&O MPPT technology increases the output capacity of solar panels by monitoring their maximum power point through disturbance and observation. To enhance energy conversion efficiency while dealing with the nonlinear dynamics of power converters, we must apply a nonlinear control approach. The purpose of this study is to develop novel first-order sliding mode control algorithms for solar energy conversion that are both dependable and efficient. A sliding mode control for nonlinear loads is being used to solve first-order buck-boost converter and THD difficulties. Furthermore, the power quality of the system was enhanced. The output of the DC–DC converter is connected to a VSI-based space-vector pulse-width-modulated inverter that generates three-phase alternating current by using space vector pulse-width modulation. The endurance and performance of the solar energy conversion system were tested using a MATLAB computer simulation.
