摘　　要：针对航空铅酸电池的特点,设计开发了一种具有多充电模式的航空铅酸电池充电器,最大输出功率为400W。阐述了充电器的总体设计方案。主功率控制电路选用了UC2846控制芯片,可以实现恒压恒流或涓流输出。充电控制电路的构建以芯片UC2909为核心,实现平均电流控制。介绍了主变压器、输出滤波电感和输出滤波电容等关键器件的选型和参数计算。研制成功的工程样机可以实现三段式充电。样机的实测结果表明:该充电器具有充电时间短,波形稳定,尖峰小,精度高等有点,便于实际使用。A high power multi-charging mode charger for aircraft lead-acid batteries is designed. Its max power is 400 W. The general design method of the proposed charger is introduced. The main power control circuit is takes the UC2846 chip. It can output constant voltage/current or tiny current. The charging control circuit uses the UC2909. It can achieve average current control. How to choose the transformer and filters. A phototype is developed. It can realize three state charges. Test results of the phototype show that the proposed charger has the advantages of short charging time, stable waveform, little peak, high accuracy and easy for practical application.
