A maximum power point control photovoltaic system

A maximum power point tracking control (MPPT) is used for a photovoltaic (PV) system in order to maximize the output power irrespective of the temperature and irradiation conditions and of the load electrical characteristics. In this paper, we consider a photovoltaic panel supplying a battery. For maximizing its output power, we have used a boost DC/DC converter controlled by a PI regulator. The synthesis of this regulator parameters has been achieved by using Bode method. For having a transfer function of the system, we have used a small signal modeling. Theoretical and simulated results are presented. Experimental results are conclusive.
