This work focuses on the optimization of photovoltaic MPPT chain, this axis is an important flaws in this field. For this we proposed a new approach MPPT and make a comparison with other approaches known in the literature. Simulation results show that our algorithm is efficient and rather complex than the other algorithms. However has a study on the stability of the DC-DC converter offer a more flexibility and stability during variation of the maximum operating point.
