Abstract: In order to increase the output efficiency of a photovoltaic generates system it is important to have an efficient Maximum Power Point Tracking (MPPT) algorithm. The constant voltage (CV) method is impossible to exact acquire the maximum power (MP) point because of some problems is not be resolved, i.e., the efficiency is very low, and only one maximum power point (MPP) is tracked in the whole tracking course. Theoretical and simulative results show that the optimal output voltage is changing with the weather. This paper describes a new variable voltage MPPT algorithm based on the actual n and Io, which is combined perturb and observe (PO) method in order to acquire the actual diode factor and reverse saturation current. The proposed control scheme and the Sepic converter are used to verify the correctness and validity of MPPT algorithm.
