为实现光伏发电应用中LCC谐振电路的最大功率点跟踪(MPPT),首先,基于傅里叶级数的动态相量法对LCC谐振电路建立了稳态数学模型.然后,基于阻抗匹配的思想,在其数学模型的基础上提出了一种以开关频率为控制变量的MPPT阻抗匹配方法.最后,根据已有文献提供的最大功率点测量矩阵为依据进行了仿真和实验,通过仿真和实验结果验证了这种阻抗匹配方法的正确性.与其它几种经典的MPPT算法比较,验证了以阻抗匹配思想为基础的MPPT方法有明显的优点.

In order to realize the maximum power point tracking (MPPT) of the series-parallel resonant con- verter (LCC) with capacitive output filter in the photovoltaic power generation, firstly, based on Fourier series, a steady-state mathematical model of the LCC resonant circuit is established using dynamic phasor. Then, according to the thought of equivalent impedance matching, a MPFF algorithm is obtained based on the mathematical model of LCC converter. Finally, in terms of measurement matrix of the maximum power which has been provided by the ex- isting literatures, this method of equivalent impedance matching is verified by the results of simulation and experiment. Compared with the classic MPPT algorithm, the MPPT algorit...
