资料介绍

为了实现无人地面车辆机载蓄电池的自动充电,设计了旋转式耦合器和全桥式串联谐振功率变换器,并对谐振电路和主电路工作过程进行了仿真分析,最终研制了一种感应式充电试验装置。系列试验结果表明:所建立的主电路仿真模型符合实际,可以指导感应充电装置功率变换器的设计;随着耦合器气隙增大,电能传输效率呈现斜率渐缓式减小趋势;所设计充电装置能够在气隙1.2mm3条件下实现蓄电池的恒流充电。

It is important to charge accumulator automatically on unmanned ground vehicles. A kind of in- ductive power charging system, based on rotary type coupler and series-resonant power converter of full bridge, is designed. The working progress of resonant circuit and main circuit is simulated. The result of experiments shows that the simulation model of main circuit is corresponding to practice and can instruct design of power converter in the future. The efficiency of power transferring decreases with coupler air gap increasing. The designed inductive charging device can charge accumulator with constant current while the air gap is 1.2 mm.
