The output power of photovoltaic (PV) arrays is influenced by changes in light intensity and temperature, making Maximum Power Point Tracking (MPPT) technology essential in PV systems. Among all MPP control strategies, the Perturb and Observe (P&O) MPPT algorithm is widely adopted due to its simplicity of implementation. However, it suffers from drawbacks including energy oscillation losses when the operating point crosses the Maximum Power Point (MPP) under steady-state conditions and poor dynamic response during sudden changes in light intensity or temperature. This paper proposes an improved variable-step P&O MPPT algorithm that dynamically adjusts the step size based on the operating point. Compared to traditional fixed-step methods, the proposed approach significantly enhances MPPT speed and conversion efficiency. Simulation and experimental results validate the effectiveness of the improved algorithm, with implementation details highlighting adaptive step-size calculation logic and reduced computational overhead.
