资料介绍

提出了一种三相应急电源快速充电控制策略,在蓄电池充电初期采用多级恒流充电,且在充电过程中引入窄脉冲放电以消除蓄电池的极化,在充电末期采用恒压涓流充电。采用移相控制零电压开关全桥变换电路对蓄电池充电,降低了电能损耗,提高了效率。仿真结果证明了理论分析的正确性和可行性。

The paper proposed a fast charge control strategy for three-phase EPS, multi- constant current charge was a- dopted at first stage, the narrow pulse discharge was used to eliminate battery polarization in the course of charging, con- stant-voltage trickle charge was adopted at the terminal stage. Because phase-shifted zero-voltage-switching full-bridge converter was introduced to the accumulator charge circuit, the power loss was reduced and the efficiency increased markedly. The simulation results are proved correct and feasible
