Abstract

This work presents the study and implementation of a multi-input dc-dc interleaved boost converter used in solar photovoltaic systems. Initially, a comparative analysis between two popular techniques used to track the maximum power point is performed to demonstrate whether controlling the PV array voltage or current has significant impact on the solar energy conversion into electricity. Due to their popularity, perturb and observe and incremental conductance are chosen and evaluated through simulation tests. Considering that the results obtained with both techniques controlling either the voltage or the current of the modules are similar, incremental conductance is implemented in and dc-dc interleaved boost converter operating in discontinuous current mode. Thus, it is possible to mitigate the partial shading effects on photovoltaic arrays, also reducing size of passive elements and providing fast transient response. Experimental results on a PV system using a digital signal processor are presented to validate the proposed approach.
