摘　　要：提出了一种采用先恒流后恒压的两段式充电方法的蓄电池智能充电器。该充电器以Buck变换器为核心,利用UC3886芯片实现平均电流模式PWM控制,并且通过一定的控制电路实现智能化充电。阐述了该充电器的充电方式、控制方法的设计以及整个电路的分析。A intelligent storage battery charger （SBC）, which adopts two-step mode charging technology, namely the constant current charging originally and the constant voltage charging subsequently is presented. A Buck converter is the central component of SBC. By using UC3886 chip, SBC carries out the average current mode PWM control scheme, and realizes intelligent charging through a certain control scheme. The charging and control schemes design for SBC and the entire circuit of SBC are discussed in detail.
