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.[SDGs]SDG7Energy harvesting; Burst-mode; Low Power; Maximum Power Point Tracking; Maximum Power Point Tracking algorithms; Output power; Performance comparison; Perturb and observe; Photovoltaic energy harvesting; Switching loss; Work analysis; Maximum power point trackersconference paper10.1109/ECCE47101.2021.95960042-s2.0-85123349548
