Control Method of Photovoltaic Maximum Power Point Tracking Based on the Theory of fuzzy

摘要：

　　Output power of Photovoltaic cells with nonlinear characteristics is af fected by temperature,light intensity and load.In orde r to im prove photoelectric conversion efficiency,maximum power point tracking (MPPT) is require d.According to the m echanism and control methods of Maxim um Power Point Tracking (M PPT),a new m odified adaptive duty cycle perturbation MPPT method which is based on fuzzy control is presented.The experim ental results show the proposed system can track the MPP quickly,exactly and steadily.
