针对应用在独立光伏系统中的超级电容模组，提出采用Buck变换器对其进行充电，在充电过程中，进行过压保护，未达到额定电压时采用扰动观察法对光伏阵列进行最大功率点跟踪（MPPT）控制，仿真结果表明了充电过程中能跟踪光伏阵列的最大功率点，且具有过压保护功能。

The buck converter is proposed to charge for the super capacitor module used in independent photovoltaic system in this paper.ln the charging process,the over-voltage protection is used.When the voltage of the module is not reach the rated voltage,the perturbation and observation method used for the maximum power point tracking (MPPT) control of PV array.The simulation results show that the maximum power point of the photovoltaic array can be tracked in the process of charging.
