摘要
叙述了一种针对标称电压为24V,容量为2.5Ah的镍氢电池组的充电器的实现。该系统摒弃传统的工频变压器,采用TOPSwitch—GX系列单片开关电源芯片,通过PWM的方法实现了对电池组进行不同速率的充电和充电状态的准确控制。
This article demonstrates the realization of a charger for Ni-MH battery with nominal voltage 24V and capacity 2.5Ah. Discarding the traditional power frequency transformer, the system adopts a single-chip switching power supply of TOP Switch-GX Family, and it achieves the accurate control on the charging of the battery with different rates and charging conditions through the PWM method.
