基于Buck拓扑的光伏充电控制器设计

摘要

介绍了一种基于Buck拓扑的光伏充电控制器,以PIC16F1829为主控MCU,实现具有MPPT和恒压充电的分段充电功能,实验结果表明,该充电控制器可充分利用太阳能电池板,具有较高的工作效率。%A PV charging controller based on Buck topology is designed in this paper,PIC16F1829 is used as the char-ging controller to realize the MPPT of the PV array and constant voltage charging of the battery.The experimental result proves that the charging controller can make full use of the PV array and has higher efficiency.
