Nabil Kahoul, Mounira Mekki . Adaptive P&O MPPT Technique for Photovoltaic Buck-Boost Converter System. International Journal of Computer Applications. 112, 12 ( February 2015), 23-27. DOI=10.5120/19719-0773
Maximum power point tracking (MPPTs) play an important role in photovoltaic (PV) power systems because it maximize the output power & efficiency of PV systems. MPPTs find and maintain operation at the maximum power point. This work presents in details implementation of Perturb and Observe MPPT using buck-boost converter. Some results such as current, voltage and output power for various conditions have been recorded. The simulation has been accomplished in MATLAB/SIMULINK software. The obtained results and the theoretical operation confirm the reliability and performance of the proposed model. It is more efficient, accurate, used rapid and low cost technique without need for complicated mathematical operations and is independent of device physics.
