摘 要
当今世界,能源问题日益突出,环境问题亦日益加剧,这其中,以使用汽油为动力的汽车所排放的尾气,占了很大比重。 近年来,大力推广新能源汽车,主要是电动汽车的使用,已经成为世界各国已达成的共识。电动汽车虽有零尾气排放、能源利用率高等诸多优点,但是其充电问题是一项短板。传统的接触式导线充电装置易发生机械磨损、接触处易产生火花、接头处由于金属氧化增加接触电阻易导致充电时发热的问题,而感应耦合能量传输(Inductive Coupling Power Transmission, 简称ICPT)式无线充电则很好的避免了这些问题,同时其可以工作在易燃易爆、潮湿高温的恶劣环境中,且充电方便,已渐渐成为电动汽车充电技术领域的发展主流。
本文通过分析感应耦合能量传输技术的国内外研究现状和实际应用现状的基础上,设计出一套基于双LCC型谐振补偿系统的电动汽车无线充电装置。首先阐述国内外无线充电装置的研究与应用现状,综合分析各种研究方案的优缺点,提出一套基于双LCC谐振补偿网络的磁耦合谐振式无线充电装置的设计方案;其次,对本方案各个模块进行原理上的分析与基于MATLAB/Simulink的仿真;最后,根据原理与仿真设计,选用合适的控制器与拓扑,设计出一套实验装置,并进行实物测试。结果表明,本装置很好的完成了3.3kW的无线能量传输,系统高效安全可靠。

Abstract
In today's world, the energy problem is becoming more and more prominent, and the use of coal and oil in fossil fuels has increased the environmental problems, with a significant proportion of the exhaust emissions from gasoline-powered cars. In recent years, vigorously promote the use of new energy vehicles, mainly electric vehicles, has become the world has reached a consensus. Electric vehicles, although zero emissions, high energy efficiency and many other advantages, but the charging problem is a short board. The traditional contact wire charging device is prone to mechanical wear, the contact is easy to produce sparks, the joints due to metal oxidation to increase the contact resistance can lead to heat problems when charging, and inductively coupled energy transmission (Inductive Coupling Power Transmission, referred to ICPT) Charging is a good way to avoid these problems, while it can work in flammable and explosive, humid high temperature harsh environment, and easy to charge, has gradually become the mainstream of electric vehicle charging technology development.
In this thesis, based on the analysis of the status quo and practical application of induction coupled energy transmission technology at home and abroad, a wireless charging device for electric vehicle based on double LCC type resonance compensation system is designed. This paper first introduces the research and application of wireless charging device at home and abroad, analyzes the advantages and disadvantages of various research programs, and puts forward a design scheme of wireless charging device. Secondly, the principle of this program is analyzed and simulink Simulation; Finally, according to the principle and simulation design of a set of experimental devices, and conducted experimental tests. The results show that the device is very good to complete the 3.3kW wireless energy transmission, the system safe and reliable.
