Abstract
Based on the analysis of the mathematical model and the output characteristics of the photovoltaic cells,a new method of combining constant voltage method with adaptive duty cycle controlling method was proposed.Aiming at the maximum power point tracking (MPPT),combining constant voltage method with adaptive duty cycle P&O algorithm were applied in tracking photovoltaic arrays maximum power point.Under changing environmental circumstances,by using the MATLAB software,simulating,training and testing the neural network,the results showed:the proposed method tracks the MPP exactly and quickly,has better control precision and improves the energy conversion efficiency of PV generation system by reducing the output power oscillation around MPP.关键词
