Abstract
In this paper, we present a system based on advanced microcontroller in which are implemented a model based on one diode of a photovoltaic generator (PV) and a MPPT (Maximum Power Point Tracking) control P&O (Perturb and Observe). We emulate a PV generator by developing the current-voltage (I / V) characteristics and power-voltage (P/V) characteristics. The integrated MPPT algorithm generates a PWM (Pulse-width Modulation) signal for the maximum power point tracking of the photovoltaic generator according with the temperature and sunshine. The power part being in development, in this phase of the work, we present and compare the (I /V) and (P/V) characteristics and the control PWM signal generated by our system with the results obtained under the Matlab/Simulink environment.
