摘　　要：本文介绍了一种基于AVR单片机的智能快速充电器的设计方法。根据充电电池取样电压和电流状态信息,AVR单片机产生合适的PWM信号,控制BUCK变换器工作,实现充电高效控制。快速充电过程中,充电电池的电压和电流取样值波动较大,为了消除这种影响,采用软件检测处理,及时确定充电结束时间,避免过充。One kind based on the AVR MCU intelligent fast battery charger design method is introduced by this article. According to the rechargeable battery sampling voltage and the electric current condition information, the AVR MCU produces the appropriate PWM signal, controls the BUCK converter working, achieves charge controlling highly effective. In the rapid charge process, the recharge.able battery voltage and the electric current sample value variation is great. In order to eliminate this influence, uses software examination processing, determines the charge closure time promptly, avoids charge excessively.
