Abstract
This paper analyses the performance of photovoltaic (PV) system in different climatic conditions and proposes an optimal topology to improve the tracking efficiency conditions. The maximum operating point is determined by the intersection point of its characteristic curves which is not always same due to losses in the system. DC-DC converters together with maximum power point tracking systems (MPPT) are used to avoid these losses. Different algorithms have been proposed for MPPT. The choice of the right DC-DC converter configuration has not been studied so widely. In this paper practical and theoretical analysis of Cuk converter with resistive load connected to PV modules with a modified Perturb and Observe (P&O) MPPT controller is done and influence of Cuk in the optimum performance of the PV system is proved.
