Maximizing Power Output: MPPT and Buck-Boost Converter Analysis in PV Applications

Abstract

Maximum power point tracking (MPPT) strategies are applied in PV applications for maximizing power and continuously evaluating the whole power point of photovoltaic (PV) modules under various atmospheric conditions. For it to be possible to match the source impedance to the load impedance for MPPT, numerous DC to DC converters (such as the Buck-boost, Boost, and Buck) are inserted between PV arrays and loads in the PV system, and their efficacy and assessments will be discussed in the remainder of this paper. All these DC-DC converters and MPPT tracking (P & O) algorithm are modelled using MATLAB/Simulink and results shows that the maximum power is enhanced with Buck-Boost converter than other dc-dc converters. © 2024 IEEE.
