摘 要

跟随着能源问题的凸显，如何才能最好的利用现有的能源，已经引起了人们的高度重视。无线电能传输作为一种新型的电能技术，是实现能源高效使用的重要途径之一。

无线电能传输技术主要有三种实现原理: 微波传输原理，磁耦合谐振原理，电磁感应原理。采用微波传输原理是可以进行远距离的电能传输的，但是其发展较为缓慢，主要是因为传输效率较低，内部结构较为复杂。电磁谐振耦合无线电能传输技术是利用磁谐振耦合进行电能的无线传输，属于电能输送领域的前沿课题，是一个全新的技术领域。而利用电磁感应原理实现无线电能传输能在比较短的距离内以较高效率传输比较大的功率，发展比微波传输和磁耦合谐振都更为成熟。

本文首先简要介绍了无线电能传输的发展历史以及国内外研究现状，对感应耦合型无线电能传输系统进行了详细分析，其结构主要包括能量发射装置和能量接受装置两大组成部分。

其次，对本文所使用的软件ANSYS也进行了简要说明。以后基于感应耦合型的原理建立了三种线圈模型，包括单层锥形线圈、空心锥形线圈和带铁芯锥形线圈，并且利用有限元分析软件的强大电磁仿真功能，对以上三种线圈各自的耦合系数进行分析，画出了在不同的气隙下各自的耦合系数的折线图。

The optimization design of wireless power transmission system

Abstract

With outstanding energy issues,how to best make use of exsisting sourse, haveattracted the attention of people. As a new power transmission technology,wireless power transmission technology,is one of the important ways to realize the efficient use of energy.

Wireless power transmission technology can achieve by three main principles: microwave transmission principle,the principle of magnetic resonance coupling,electromagnetic induction principle. Using microwave transmission principle can achieve long-distance wireless power transmission,but the tracking system and its complex and the transmission efficiency is low,which seriously hindered the development of it. Electromagnetic resonant coupling wireless power transmission technology use magnetic resonance coupling to achieve wireless transmission,belonging to the electric energy frontier transportation field,is a new technology field. Using electromagnetic induction principle can achieve wireless power transmission at close range (1cm or less) to a larger more efficient power transmission,and the development of it is more sophisticated than the previous two.

This paper begins with a brief introduction to the history and present situation of research and development of wireless power transmission, for inductively coupled wireless power transmission system is analyzed in detail, including the structure of energy and energy transmitting device accepts two component devices.

Secondly, the software ANSYS used herein are briefly described. After the model based on the principle of inductive coupling to establish a single cone-shaped coil, hollow conical coil and coil with three kinds of cone-shaped coil core model, using finite element analysis software, a powerful electromagnetic simulation capabilities of these three respective coupling coil coefficient analysis shown in FIG different respective gap line coupling coefficient.

Keywords: wireless power transmission, electromagnetic induction, finite element, design optimization
