摘要
本文提出了一种基于电流模式的市电、直流与蓄电池三电源切换电路的设计。实测结果表明该电路可按供电优先级灵活地进行电源切换,并且响应灵敏,工作可靠。
The power switching circuit based on current model to switch among the power supplies of AC （220V, 50Hz）, DC （9-18V） and lead-acid batteries is presented in this paper. Experimental results show that the power supplies could be switched automatically according to a certain priority, with sensitive response and reliable operation.
