【摘要】：随着清洁能源的开发与利用,电动汽车以其绿色零污染的优点逐渐进入人们的视野里。目前限制它大范围推广的一大弊端就是传统充电模式无法达到人们的预期效果。非接触电能输电技术以非电气连接的方式进行能量的传输,其灵活、安全等特点逐渐成为了学者们的一个研究热点。本文对感应耦合式(ICPT)无线电能传输系统进行研究分析,主要内容如下:首先,介绍了当前非接触电能传输技术的研究现状及应用情况,对比分析了三种主流的无线输电技术的优缺点并选择ICPT技术作为本文的研究对象。其次,对ICPT系统的结构组成、工作原理进行分析,使用互感模型对整个系统的进行建模分析,并对四种经典的单级补偿电路的优缺点分别分析。接着,将LCL谐振变换器作为ICPT系统的谐振补偿拓扑,研究其工作原理,推导一些参数的计算公式,对其独有的恒流、恒压特性并通过仿真加以验证。最后,对ICPT实验系统尝试搭建,对其核心部分可分离变压器的结构、磁芯材质、线圈型号等进行对比分析并选出最优,不再使用传统的E型结构转而搭建一种更利于完成整体系统的搭建并对实验结果实测分析,系统传输效率达到50%。
[Abstract]:With the development and utilization of clean energy, electric vehicles (EV) come into view with its green zero pollution. At present, one of the disadvantages of limiting its wide spread is that the traditional charging mode can not achieve the desired results. Non-contact power transmission technology transmits energy by non-electrical connection. Its characteristics of flexibility and safety have gradually become a research hotspot of scholars. The main contents of this paper are as follows: firstly, the current research status and application of contactless power transmission technology are introduced. The advantages and disadvantages of three mainstream wireless transmission technologies are compared and the ICPT technology is chosen as the research object of this paper. Secondly, the structure and working principle of ICPT system are analyzed, the mutual inductance model is used to model the whole system, and the advantages and disadvantages of four classical single-stage compensation circuits are analyzed respectively. Then, the LCL resonant converter is used as the resonant compensation topology of the ICPT system. The working principle of the converter is studied, and the calculation formulas of some parameters are deduced. The characteristic of constant current and constant voltage of the converter is verified by simulation. Finally, try to build the ICPT experimental system, compare and analyze the structure of the core separable transformer, core material, coil type and so on, and select the best. Instead of using the traditional E structure instead of building a more conducive to the completion of the overall system and analysis of the experimental results, the transmission efficiency of the system reaches 50%.
