MPP TRACKING DEVICE BASED ON A NOVEL ADAPTIVE P&O METHOD IMPLEMENTED AT LOW COST WITH AN ARDUINO UNO FOR PHOTOVOLTAIC SYSTEMS

Resumen de: WO2026187227A1

: The present invention proposes an innovative maximum power point (MPP) tracking device that is optimized for photovoltaic (PV) systems. Based on an improved perturb-and-observe (P&O) algorithm and integrated proportional-integral (PI) control, this device integrates a maximum power point tracking (MPPT) method with a mechanism having an adaptive step size. Replacing the traditional voltage perturbation with a current perturbation considerably improves tracking accuracy and efficiency, thus reducing energy losses. The assembly is implemented at low cost on an Arduino Uno microcontroller using a C++ code that is optimized to integrate the PI control directly, eliminating the need for external components. This solution offers enhanced performance, a simplified architecture and reduced costs, outperforming not just conventional methods but also advanced techniques such as particle swarm optimization (PSO) and fuzzy logic control (FLC).
