摘要：反激式转换器实现电流限制电源铅酸电池充电。 MAX668 PPM的控制器限制输出电流，回扫变压器，提供电压的上方和下方的电池电压输入的隔离和灵活性。 MAX4375电流检测放大器监视充电电流和使用其内部设计的阈值以下的反激式转换器，可以切换到一个较低的充电电压涓流充电模式比较。Maxim > Design Support > App Notes > Battery Management > APP 621 Keywords: lead-acid batteries, battery, trickle-charge, boost converter, flyback converter, converter Aug 26, 2011 APPLICATION NOTE 621 Simple Circuit Charges Lead-Acid Batteries Abstract: A flyback converter implements a current-limited power supply to charge lead-acid batteries. The MAX668 PPM controller limits the output current, and the flyback transformer provides isolation and flexibility for input voltages both above and below the battery voltage. The MAX4375 current-sense amplifier monitors the charging current and uses its internal comparator that below a designed threshold the flyback convert……
