Desenvolvimento de um caracterizador para arranjos fotovoltaicos utilizando conversores ćuk em paralelo

Abstract

Due the technology development ad the search by leisure, installations of photovoltaic systems are in constant increasing. However, photovoltaic installations are exposed to several problems, like heating, shading, structural damage, bypass diode fail, among other. This way, to verify the problems, or to realize prevent actions, it can utilize a photovoltaic characterizer, that is able of to trace a characteristic curve of current by voltage (I-V) of a photovoltaic module. Therefore, there are several characterizer topologies in the literature, that it will be briefly discussed in this work. And will be highlighted the characterizer that to utilize statics converters of Ćuk topology operating in parallel, that there is a segment of project of your elements. From that, the simulation results are presented, where is possible to verify the operation of the characterizer.
