摘要
光伏系统的输出因受外界影响,无法长时间稳定供电,因此必须借助光伏充电控制器解决这一问题。为了保证在不同条件下输出功率最大,研究追踪最大功率点(MPPT)的光伏充电控制器,结合光伏电池的输出特性和充放电特性,设计完成基于MPPT的光伏充电控制器。经试验测试,该控制器能保证输出电压幅值稳定,追踪效率在0.95以上,充分提高了太阳能的利用率。
Affected by the outside world,the output of photovoltaic system can’t supply power stably for a long time. It’s a must to use photovoltaic charging controller to solve this problem. In order to ensure the maximum output power under different conditions,the photovoltaic charging controller tracking the maximum power point( MPPT) is studied. Combined with the output characteristics and charging and discharging characteristics of photovoltaic cells,the MPPT based photovoltaic charging controller is designed. Through the test,the controller can ensure the output voltage amplitude to be stable,the tracking efficiency is more than 0. 95,and fully improve the utilization of solar energy.
