在光伏发电系统中光伏电池板是产生电能的装置，光伏电池运行受外界环境温度、辐照度等因素的影响，呈现出典型的非线性特征。外界条件不同时，光伏电池可运行在不同且唯一的最大功率点上。分析了最常用的最大功率点跟踪方法。并给出了一种新的最大功率跟踪方法，新方法能够快速跟踪到最大功率点，并且解决了跟踪过程的振荡问题。最后通过Matlab／Simulink仿真验证了控制有效性，得到了较好的输出波形。

Photovoltaic cells are devices for generating electric energy in the photovoltaic power generation system. The photovoltaic cells under operation will present a typical non-linear characteristic with the influence of the environ-mental temperature,irradiance and other factors. Moreover,under different external conditions,photovoltaic cells are able to run on different and unique maximum power point. The most commonly used method of maximum power point tracking was analyzed in this paper,and a new tracking method of maximum power was proposed which could realize the maximum power point fast tracking and solve the oscillation problem during the tracking process. The con-trol effectiveness is verified by Matlab/Simulink simulation,and good output waveform is obtained.
