An Improved P&O MPPT Method Using Boost Converter for Photovoltaic Applications

A maximum power point tracker is required to improve the power conversion efficiency of the solar photovoltaic generation system (PVGS) and ensure maximum power transfer from panel to the load through continually matching their internal resistances. In this study, an improved fixed step-size perturb and observe (P&O) maximum power point tracking (MPPT) has been proposed and analysed using MATLAB/Simulink. Duty cycle was used to control the DCDC boost converter's switching signal in the system configuration. Several key performance indicators to evaluate the suitability of the proposed algorithm were tested. It was found that the algorithm has excellent tracking efficiency above 99% and is capable of tracking the maximum power point (MPP) correctly at a lower time interval. The overall efficiency of the system is remarkably good, with a value higher than 97%. The proposed algorithm is, therefore, appropriate for photovoltaic (PV) applications.
