Dynamic behavior overview of three conventional dc/dc converters used in PV MPPT system
Main Article Content
Abstract
To improve the performances of such perturbative maximum power point tracking (MPPT) algorithm, the real-time optimization of the algorithm designed parameters is used. Such optimization depends on the dynamic behavior of the whole photovoltaic (PV) MPPT system, and more especially, on that of the adopted dc/dc converter topology, which is used to realize the MPPT function. Therefore, the present paper shows an analytical study about the dynamic behavior of three conventional dc/dc converter topologies: boost, buck and buck-boost. For that, we establish the small-signal model for three cases of PV MPPT system that are composed each one with each of the above topologies, and then the transfer functions in the Laplace domain are drawn. In this approach, the dynamic behavior is defined by the natural frequency and damping factor parameters of the above systems. The comparison based on the variation of these two parameters, allows us having an overview about the dynamic behavior of the under study systems for the aim to implement a more efficient real-time MPPT algorithm.
