摘要
论述了利用Boost电路对光伏电池进行最大功率点跟踪(MPPT)的原理,分析了Buck电路和Boost电路在MPPT电路中的优缺点,提出了一种单片机控制的,以Boost电路为核心的MPPT系统,并对以蓄电池为负载的系统进行了的实验研究。结果表明,该系统在各种辐射强度下均明显增加了输出功率。
The paper introduces the principles of photovoltaic maximum power point tracking (MPPT) using Boost con-verter and gives brief comparison between the Buck and Boost converter in MPPT. A microcontroller-based MPPT system with Boost converter is proposed. Experiment research is proceeded to the MPPT system with battry-load.Experiment re-sults show that output power increases obviously under different solar radiation.
