| 摘 要： | 针对太阳能光伏发电系统中的最大功率跟踪问题,提出了一种基于AVR单片机控制的新方案。系统运用三重Boost DC/DC变换器对光伏电池输出功率进行有效调节,采用最优梯度控制算法搜索最大功率点。对该系统进行了Matlab/Simulink仿真,并在硬件电路的基础上进行了试验。结果表明,该系统能较快地跟踪太阳能的最大功率,并具有较高的跟踪精度。

| Abstract: | A new scheme is proposed for the photovoltaic maximum power point tracking (MPPT) system,which is controlled by a AVR microcontroller-based unit.The system uses three plies Boost DC-DC converter to efficiently adjust output power of the system.Optimal gradient method is used for searching maximum power point.The model is tested by using Matlab/Simulink software,and the test has been done on the harware.The results show that the system can track the maximum power point effectively and accurately. |
