摘要 介绍了一种基于DSP的新型光伏电源MPPT控制方法,即将太阳能电池板和MPPT系统作为一个整体,直接根据负载的功率变化来控制Cuk变换器的占空比以实现最大功率点跟踪.实验表明:该系统在日照强度及环境温度大范围变化时仍然可以快速、准确地跟踪到太阳能电池的最大功率点,并具有较好的稳定性. A new MPPT (Maximum Power Point Tracking)control of photovoltaic power system based on DSP is introduced, which takes the solar cell board and the MPPT system as a whole. According to power change of the load, the dutyfactor of Cuk converter is controlled directly to realize MPPT control. The result indicates this system can fast track the photovoltaic power MPP accurately and rapidly and has good stability when there is a wide scope change of sunshine intensity and ambient temperature.
