摘　　要：该充电器是基于专用集成电路芯片UC3906与UC3823设计的。UC3906基准电压的大小随环境的温度而变化,且变化规律与铅酸蓄电池的温度特性一致,充电器可保证电池在很宽的温度范围内精确充电,延长电池的使用寿命;采用UC3823PWM控制电路进行脉冲充电,可以消除充电过程中的极化现象,提高充电效率。The charger on switching circuit for lead-acid cell was designed by using UC3906 and UC3823. UC3906 datum voltage can change with the environment temperature,and the change rule is the same as the lead-acid cell＇s. It can accurately charge the battery in a wide temperature range,and the life of the battery can be prolonged,pulse charging was used on UC3823 PWM control which can automatically eliminate the lead-acid cell＇s polarization phenomenon,and improve the charge efficiency.
