Abstract: This paper focuses on the development of a voltage-based PV MPPT controller. The proposed controller has been used to track the maximum power of PV generator system composed of Solarex MSX-60W PV panel fed by a DC-DC boost converter drive using the proposed voltage-based MPPT powering a resistive load. The proposed MPPT which uses only a voltage sensor has been implemented and validated using MATLAB/Simulink environment. Simulation obtained results using the proposed MPPT controller and the two sensors IC MPPT prove that the performances of the proposed single sensor MPPT are very close to those of the two sensors IC MPPT regarding dynamic, static and tracking accuracy performances. In addition, the proposed voltage-based MPPT controller can effectively track the maximum power using only one sensor compared to the classical MPPTs using two sensors reducing by the way the cost and the complexity of the PV system.

Keywords: PV; maximum power point tracking; MPPT; single sensor; DC-DC; incremental conductance.
