“…[2] Among these renewable energy resources, solar energy offers a promising solution to the world's energy needs due to its free availability, clean behavior, and unlimited quantity. [3] For these reasons, photovoltaic (PV) systems are now widely used in diverse applications, such as solar battery charging, [4][5][6] solar water pumping, [7] electric vehicle power systems, [8] nanosatellite power systems, [9] and even robotic power systems. [10] Although PV systems have several advantages as mentioned previously, they also have some disadvantages, such as low PV power conversion efficiencies and high installation costs.…”

This article presents a low‐cost maximum power point tracking (MPPT) charge controller designed to efficiently charge solar batteries using a simple and robust MPPT method, while providing protection against over‐currents and over‐voltages. The proposed MPPT approach utilizes a modified Incremental Conductance (INC) algorithm adapted to low‐cost embedded controllers, as it avoids all the mathematical division calculations typically used in the conventional INC algorithm. It also introduces a modified step size based only on photovoltaic (PV) power change to enhance tracking accuracy and convergence speed. Furthermore, to reduce the stress and switching losses of DC–DC converter, a feedback control with two proportional and integral (PI) compensators is also used to control both the PV voltage and to protect the battery from over‐currents using PV power limitation technique. Simulation results, carried out under MATLAB/Simulink, demonstrate the good performance of the proposed control scheme regarding any variations in atmospheric conditions, both for the MPPT control and for the battery charge control. Finally, a processor‐in‐the‐loop (PIL) test using a low‐cost Arduino MKR ZERO board is also performed to verify the hardware implementation of the proposed method. PIL results are in totally accordance with MATLAB/Simulink simulation results, which further proves the effectiveness of the proposed method.
