中文摘要：

此处研究了一种基于电磁感应原理的取能电源。首先采用特殊磁性材料制成取能单元,电力电缆穿过取能单元;其次通过能量管理单元经整流、滤波、DC/DC变换将取能单元输出的交流电能变成5 V;为解决传统取能电源的死区问题,引入锂离子电池作为备用单元;最后,基于STC15F2K60S单片机设计的电源管理单元,通过监测电池电压和输出电压来合理分配能量管理单元和备用单元作为输出的工作次序。

英文摘要：

An induction power supply scheme based on the principle of electromagnetic is studied.Firstly, an induction unit is made by the special magnetism material and passed through by cables.Then the AC output energy from the induction unit is rectified ,filtered by the energy management unit, and transformed to S V by DC/DC device.Lithium ion battery is used as the backup unit to eliminate dead zone which existing in traditional induction power supply.Finally,a power management unit based on STC15F2K60S decides the energy management unit or the backup unit to be the ultimate output through detecting battery voltage and output voltage.
