摘要
提出了一种太阳电池充电器的设计方案,为用户提供锂电池和镍电池两种充电选择。太阳电池板的输出通过降压开关稳压器LT1777转化成稳定电压为充电模块MAX1501供电。系统整体的控制功能由微处理器PIC16F877A完成。本设计成本低、效率高,有良好的应用前景。
A solar powered battery charger was introduced in this paper, which gave the user the choice of charging either lithium or nickel based batteries. The output of solar panels was converted into a stable voltage to power the charging unit MAX1501 by using the step-down switching regulator LT1777. The control function of the whole system was implemented with the microcontroller PIC16F877A. The design has broad application prospects due to its low cost and high efficiency.
