中文摘要：无线电源是面向不易更换电池的恶劣环境下工作的移动终端开发的无线充电系统。发射端通过LC电路将交变电能以130 k Hz的电磁波方式传输到接收端的LC电路上再转化为直流电给电池充电。本系统利用安培定律电生磁原理和电磁感应定律的磁生电原理在发射线圈和接收线圈间生成电磁耦合区免除电路直接接触而实现电能无线传输。系统传能过程中发射端和接收端通过电磁波信号实现实时双向通信,通过分析不同负载的阻抗引起的电磁波变化情况而调整相应的工作状态。本系统研究旨在提高无线电源系统的充电效率和高效的智能检测功能。实验证明,本系统已实现对电子设备高效率无线快速和慢速充电,并能对无线电源系统作出高效的智能检测。电路优化设计后接收机可方便地植入电子设备中,在物联网环境下本系统有广泛的工程应用。

外文摘要：Wireless power supply is developed for the mobile terminal system in which the power supply is not easy to replace, which is a wireless charging system based on the principle of electromagnetic induction. Transmitter transports the alternating power loads in the way of 130 kHz electromagnetic wave through the LC circuit to the LC circuit of the receiver, and then converts into the direct current charging the battery. Using the principle of electricity generating magnetism of the ampere＇s law and magnetism generating electricity of the electromagnetic induction law, electromagnetic coupling region was generated between the transmitting and receiving coil, realizing wireless transmission of electric power by avoiding direct contact of circuits. In the energy transfer processing, transmitter and receiver can realize the real-time both-way communication by the electromagnetic wave and adjust corresponding working condition through the analysis of electromagnetic wave changes caused by different load impedance. The system research aims at improving the charging efficiency and efficient intelligent detection function of the wireless power supply system. The experimental results show that the system has realized the wireless fast and slow charging of the electronic equipment, and can make efficient intelligent detection to the wireless power supply system. The receiver can be easily implanted electronic devices after the optimization design of circuit; the system has widely engineering application in the environment of the Intemet of things.
