Comparative Study of the Electronic Performance of DC / DC Photovoltaic Converters (BOOST and SEPIC)

The obj ective of this work is to contribute to the study of a photovoltaic system operating at its maximum power and energetically autonomy. The case studied in this work concerns the intelligent control of an autonomous photovoltaic system. In this sense, and in order for the photovoltaic system to operate at its maximum power, it must include an adaptation stage associated with an MPPT algorithm. In our case, we have studied the functioning of the photovoltaic cell and the DC-DC converters (BOOST and SEPIC) in the production, conversion of the photovoltaic electric energy, and then having the effect of the algorithms of Intelligent MPPT control on these converters at the temporal response, the wave ripple and the efficiency of the power transmitted by them.
