The connection between a photovoltaic array and a load is still an interest subject of research. The impedance matching between a PV array and a load is a technological problem that basically means the maximum power transfer from a PV panel to a load. Although there are many works devoted to the problem of the maximum power point tracking (MPPT) in a PV array, only few of them deal with the nature of the power interface while most of them focus on different types of tracking algorithms. The problem is addressed in this study by a systemic approach from a power interface point of view in order to obtain high levels of efficiency, reliability and flexibility. Moreover, the simulations and experimental results prove that the proposed system gives a fast response and is suitable for rapidly changing weather conditions. In steady state, the tracking of the maximum power point with the proposed system is very effective or efficient and the quality of the signals is substantially improved. In addition, the output power fluctuation is also reduced, which is a major problem in all MPPT maximum power point trackers and especially the traditional ones, and reducing the output power fluctuation is a goal. adapting it to the load.
