摘要
针对现有充电器存在的问题和不足,设计了一款基于PIC单片机的智能充电器.可利用单片机功能的灵活性对电池快速充电,通过按键对充电器进行设定,具有良好的人机交互.单片机可以直接生成半桥波,降低成本,并可通过采样电压和电流直接控制占空比来改变输出电压.
According to existing defects of the charger,a new intelligent charger based on PIC single chip microcomputer（SCM） was designed. The battery can be charged quickly by taking advantage of flexibility of SCM, and the changer can be set by keyboard, which presented a good human-computer interaction. The SCM can directly produce half-bridge wave and reduce the cost. Through controlling the duty cycle of sampled voltage and current ,the output voltage can be changed.
