Abstract

The output power of the photovoltaic is a kind of nonlinear function which is influenced by the intensity of sunlight and internal junction temperature. In the external environment stable situation, photovoltaic, the component exists only the maximum power output point. This paper analyzes the output characteristics of solar photovoltaic array and the advantages and disadvantages of MPPT method, and put forward a kind of improved conductance increment method on this basis. The improved conductance increment method combines the traditional conductance increment method and the constant voltage tacking method. The system is able to steadily and fast track the maximum power point and the result owns high tracking precision. Under various situations, especially the adverse situation in which the sunlight changes suddenly and so on, it has high adaptive ability and can realize the maximum power point tracking to the photovoltaic cell.
