A new maximum power point tracking approach for decreasing convergence time

This study presents a new maximum power point tracking (MPPT) approach for solar panels. By using voltage current characteristic of solar panel, some analytical approaches have been developed. With the help of this approach, determination of initial operation point has been improved. In other words, this point has been determined by making some assumptions. Thus, one of the challenging tasks related to MPPT, convergence time is reduced. Benefits of developed approach have been shown by making a comparison with the Perturb and Observe (P&O) and Incremental Conductance (IC) algorithm. In this context, a low power boost converter has been designed with direct duty control in order to verify the proposed approach. Experimental results show that proposed approach performs better than conventional ones. While convergence time is high in case of P&O and IC usage, with proposed approach, it is reduced remarkably. Besides, steady state oscillation is almost eliminated in proposed approach.
