摘要
影响太阳能移动电源转换效率的主要因素是太阳能电池板的效率、是否具有最大功率跟踪功能、二次转换电路的效率。本文设计的太阳能移动电源,采用处理器来跟踪太阳能电池板的最大功率点,并根据最大功率点对锂电池充电电路进行优化设置,使太阳能电池始终运行在最大功率点,实现了太阳能移动电源的效率最大化。
The main factors affecting transfer efficiency of solar mobile power supply are solar panel efficiency, Maximum Peak Power Tracking function and secondary conversion circuit efficiency. In order to accomplish high conversion efficiency, a new system design is proposed. This solar mobile power supply in this paper can realize Maximum Peak Power Tracking for solar panel by MCU, optimize lithium battery charging circuit, maximize the solar cells.
