Photovoltaic (PV) energy is one of the most important energy resources since it is clean, pollution free, and sustainable. Maximum Power Point Tracking (MPPT) is used in photovoltaic (PV) systems to maximize the photovoltaic output power, irrespective of the temperature and radiation conditions. In MPPT system, the PV output power is fed directly to dc/dc converter and the output of MPPT control is used to control the dc/dc converter in order to operate at the maximum possible power point (MPP). In this paper it is proposed to track the MPP in PV module using incremental conductance algorithm. CUK converter is used as dc/dc converter to achieve the power/voltage level conversion. The MPPT system has been simulated using MATLAB/Simulink software to track the maximum output power from PV array and charge a battery bank. Simulation results show that the proposed MPPT system is capable of maximum power tracking of the PV array as desired.Sida from Sweden
