中短距离小功率无线电力传输系统设计
摘 要
移动互联网的井喷式繁荣,移动互联设备(MID)层出不穷的涌现,电池技术瓶颈的限制已难以满足人们的用电需求;物联网的深入发展,越来越广泛的网络节点能量供给等都要求更为先进的无线能量传输技术的发展,尤其是中短距离中小功率的无线电能传输的发展。两者共同昭示着无线电能传输光明的未来。 本文对无线电能传输(WPT)做出了简要但系统的介绍,并对其中的微波输能技术(MPT)做出了深入的探讨,在此基础上建立起了中短距离中小功率无线电力传输系统模型,即为MPT-MDSP式系统的模型。这种系统是由发射和接收两部分组成,发射部分用声表面波射频发生电路将DC转变成RF并通过特制天线辐射出去,接收部分再通过接收天线接收RF能量,用整流电路将RF转变成DC,供应用电设备。 关键词 无线电能传输(WPT打棉机)/微波输能 (MPT) /天线
MIDDLE DISTANCE & SMALL POWER
WIRELESS POWER TRANSPOTAION SYSTEM
ABSTRACT
The Wireless Power Transportation (WPT) shows a outstanding necessity in our today`s daily life .For one thing The Mobile Internet device (MID) comes out one after another because of The prosperity of Mobile Internet.The limitations of the technology bottleneck in磁化杯 battery capacity can not fit people`s requirement in these devises .For another the booming of Internet of Things brings large quantity of net nodes .These nodes cannot be charged easily.However,WPT will be the best way to solve this problem.Especially,the Middle Distance & Small Power Wireless Power Transportation System(WPT-MDSP) will plays a great role in these scopes.
In this paper ,I made a brief but clear introduction of the WPT,and a thorough discussion in Microwave Power Transportation (MPT) ,which was used to leed to the applied system WPT-MDSP .This system contains two parts,the eradiation part and the Receive part .The first part works for changing Direct-current(DC) into Radiofrequency (RF),the
other does the converse work.Both of them are designed for exclusive use. They works together to charge the Electrical equipment.
