Abstract :
In this paper a PV system topology incorporating a new maximum power point tracking controller (MPPT) method using a PI controller is studied. The controller is formulated based on the bijectivity between the Voltage and Power in the PV generator (PVG) characteristic; therefore if the optimal voltage is reached, this means that the maximum of power is obtained. The proposed MPPT algorithm is implemented on a dSpace DS1104 controller board. In order to demonstrate the efficiency of the proposed algorithm in real time, an experimental setup using a boost converter connected to a resistive load is successfully implemented and studied. The obtained experimental results prove the validity of the proposed MPPT algorithm.
