研究与传统扰动观察法和Fibonacci搜索法相比，能够提高输出效率的基于对分搜索区间消去的最大功率跟踪算法。这种算法在程序执行前需要计算温度或光照强度的变化率，对于温度或光照强度的变化率超出允许值时才会执行最大功率搜索。程序开始前设定一个搜索精度和初始不定区间，在进行每一次最大功率搜索时都需要重新计算不定步长。为了减小系统波动，当环境变化后，重新搜索最大功率时电压当前点取上一次记录的最大功率点对应的电压值。通过仿真分析，该算法在搜索最大功率时响应速度快、执行效率高，后续输出能一直保持最大功率值。

This paper introduces a kind of maximum power tracking algorithm based on dichotomous search interval elimination.Before the procedure execute this algorithm needs to calculate the rate of change of temperature and light intensity.Only when changes in temperature or light intensity exceed the allowable values, will it perform maximum power search.Furthermore, it needs to set an initial search accuracy and initial interval before the begin-ning of the procedure.Every time the maximum power search needs to recalculate uncertain step.In order to re-duce the fluctuation of system voltage, the initial voltage in the research set at the last recorded maximum power point voltage value when the environment changes.Finally, through the simulation analysis, the algorithm in search of the maximum power has fast response and high efficiency.Subsequent output can keep the maximum power val-ue.Under the same conditions, compared with the traditional perturbation & observation method and Fibonacci search method, it can improve the output efficiency.
