Abstract :
The paper proposes an algorithm for tracking the maximum power point of a PV source which is based on the voltage-hold perturbation and observation tracking of the maximum power point during atmospheric changes. The algorithm overcomes the major tracking limitations and produces improved results compared with the standard MPPT algorithms which were reviewed briefly as a background. The proposed algorithm has been implemented practically by using eZdsp™ F28335 to control the DC/DC buck-converter under different irradiances.
