摘　　要：为简化变化工况下光伏组件最大功率跟踪的计算,详细推导了变化工况下光伏组件输出特性超越方程的简化求解过程,并以该简化光伏组件输出模型为基础,结合典型的Boost升压电路,利用扰动观察法构建了基于Matlab平台的最大功率跟踪模型,给出了辐照度和温度变化条件下光伏组件最大功率跟踪的仿真结果,并与理论计算结果进行了对比分析,结果表明变化工况下所建最大功率跟踪模型的平均相对误差在1%以内,证明了所建模型的有效性和准确性。In order to simplify the calculation of maximum power tracking of photovoltaic modules under changing conditions, the simplified solving process of transcendental equation of output characteristics of photovoltaic modules under changing conditions is deduced in detail. Based on the simplified output model of photovoltaic modules, combined with typical Boost boost circuit, a platform based on MATLAB is constructed by using pertur-bation observation method. The maximum power tracking model is presented. The simulation results of maximum power tracking of photovoltaic modules under the conditions of irradiance and temperature change are given and compared with the theoretical results. The results show that the average relative error of the maximum power tracking model under the changing conditions is less than 1%, which proves the validity and accuracy of the model.
