摘要

对于许多低功率系统来说，太阳能是可再生能源的重要来源。将电力消耗水平与供电水平相匹配，可以大大提高电力利用效率。本文提出了一种源跟踪电源管理策略，该策略通过负载匹配使给定的太阳能轮廓下的面板总能量输出最大化。通过大量的测量验证了功率效率。与传统的太阳能供电系统相比，我们的负载匹配策略使执行图像处理和无线通信任务的便携式系统的功率利用率提高了132%。

Maximizing efficiency of solar-powered systems by load matching

Solar power is an important source of renewable energy for many low-power systems. Matching the power consumption level with the supply level can make a great difference in the efficiency of power utilization. This paper proposes a source-tracking power management strategy that maximizes the panel's total energy output under a given solar profile by load matching. The power efficiency was validated by extensive measurement. Compared to a conventional solar powered system, our load matching strategy improves the power utilization by 132% for a portable system performing image processing and wireless communication tasks.
