| 摘 要： | 设计了一种电能收集充电器模型，该充电器的核心为直流电源变换器，将从直流电源中吸收的电能转移到可充电电池充电中．系统根据输入电压不同采用HT7712和HT7750来构建充电控制电路，通过HT46E47单片机进行功率最大点的监测．直流电源输入电压为20V时候，实现以最大144．95mA的电流向可充电池充电；直流电源电压下降到0．13V时，系统依然实现对可充电池充电；同时系统具有实现自动启动充电等功能．

| Abstract: | This paper presents a model of power collection charger. The core of the charger is a DC power converter, which shifts the electricity power from DC power to the rechargeable power batteries. According to the different input voltages, HT7712 and HT7750 chips are used to build charge control circuit. The single chip microcomputer of HT46R47 is used to monitor the maximum power point.When the input DC voltage is 20 V, the system charges the rechargeable battery at the maximum current of 144.95 mA; while the DC voltage is down to 0.13 V, the system still charges the rechargeable battery. The system also has the function of automatic start of charging. |
