摘要
采用单片机控制系统实现最大功率点跟踪(M PPT),着重对最大功率跟踪控制中DC-DC变换器的原理和控制方法进行了研究和实验,采用了升降压式(Buck-Boost)DC-DC转换电路[3]来实现最大功率点跟踪,该方法电路简单、软硬件结合、控制方法灵活,明显提高了太阳电池充电系统的整机效率.
This paper describes the method of MPPT (maximum power point tracking) with MCU controlling system in photovoltaic system, especially introduces the techniques and principle of DC-DC conversion. MPPT is implemented with a Buck-Boost topology. The system is simple with good response speed. And the efficiency of system is approved apparently with the method.
