Description

最大功率点跟踪(Maximum Power Point Tracking，简称MPPT)系统是一种通过调节电气模块的工作状态，使光伏板能够输出更多电能的电气系统能够将太阳能电池板发出的直流电有效地贮存在蓄电池中，可有效地解决常规电网不能覆盖的偏远地区及旅游地区的生活和工业用电，不产生环境污染。

MPPT控制器主要功能：检测主回路直流电压及输出电流，计算出太阳能阵列的输出功率，并实现对最大功率点的追踪。扰动电阻R和MOSFET串连在一起，在输出电压基本稳定的条件下，通过改变MOSFET的占空比，来改变通过电阻的平均电流，因此产生了电流的扰动。同时，光伏电池的输出电流电压亦将随之变化，通过测量扰动前后光伏电池输出功率和电压的变化，以决定下一周期的扰动方向，当扰动方向正确时太阳能光能板输出功率增加，下周期继续朝同一方向扰动，反之，朝反方向扰动，如此，反复进行着扰动与观察来使太阳能光电板输出达最大功率点。
