Abstract
Achieving high maximum power point (MPP) tracking efficiency and reducing converter switching losses are essential to maximizing output power for low-power photovoltaic (PV) energy harvesting applications. This work analyzes the performance of a recently-proposed burst-mode maximum power point tracking (MPPT) algorithm compared to the established perturb and observe (PO) MPPT algorithm. Overall, switching losses are reduced with burst-mode operation by actively switching only for a fraction of the operating time. The practicality of the burst-mode MPPT concept is validated through experimental results and the algorithm is verified through simulation. Simulation results indicate a slightly higher tracking efficiency than PO MPPT both under low and high light intensities. During two separate intervals with a multiple-PV/multiple-converter system, 99% tracking efficiency is reached with burst-mode MPPT; while PO MPPT achieved tracking efficiencies of 96 and 97% © 2021 IEEE.
