Abstract:
In accordance with the current needs for obtaining the energy resulting from an increasing energy demand, and where one of the most used energy sources are hydrocarbons which harm the environment, it becomes essential to look for sources of energy more friendly to the environment environment, as are renewable energies. In accordance with the above, one of the starting hypotheses of this thesis is to improve the performance of photovoltaic systems used in public luminaires by using a single switched converter, and create an innovation model that allows the link between the area scientific and industrial area and in this case seek the commercialization of the single switched converter. The generation of a new model of innovation and the generation of a new converter structure together with its mathematical modeling and application allow to improve the performance of a photovoltaic system, are the two main themes studied in this thesis as mentioned in the previous paragraph. Based on previous ideas presented in the state of the art, a converting structure is achieved, a primordial point of this thesis, called bidirectional versatile buck-boost switched converter, in which two types of analysis are carried out by applying the control in sliding mode one for mode diurnal and another for night mode in both cases counting with complex switching surfaces, which allowed to improve the performance of a photovoltaic system, validated by experimental measurements, showing the advantages with which this converter has against other converters. As in the case of the converter structure, the creation of a completely new model of innovation for renewable energies was carried out through previous studies presented in the state of the art. This model has the particularity of being easily adapted for the realization of any other type of innovation model because it is explained in detail step by step for its realization.
