摘要
针对目前光伏系统最大功率点跟踪方法普遍须要同时采集光伏电池输出电压信号和输出电流信号这一情况,文章提出了一种只须要检测光伏电池输出电压的控制方法,该方法采用占空比扰动法的工作模式,去掉了电流采样电路,简化了系统结构,并在saber环境下进行了仿真试验。最后通过对仿真结果的分析,证明了提出的光伏系统最大功率点跟踪方法的可行性和准确性。
Comparing existing photovoltaic system maximum power point tracking（MPPT） techniques that collect both voltage signal and current signal of solar cell output, a new MPPT control method that only measures output voltage of PV is put forward, which adopts the duty cycle perturbation method to simplify the system by removing the current sampling circuit. The method has been simulated in the saber. Finally, the analysis of the simulation results proves the feasibility and accuracy of this method.
