Abstract :
This paper presents a new solution to control the PV voltage following a reference provide by an external algorithm and to mitigate the oscillations in the bulk voltage. The implementation is compared with other techniques its advantages are demonstrated. The sliding mode control stability is validated for the chosen surface ensuring a good behavior in all operation range of the PV panel. Finally, simulations are used to show the effectiveness of the solution in presence of changes in the irradiance level and sinusoidal oscillations in the bulk voltage.
