WPT/WRC磁耦合谐振式无线能量传输研究

摘要首先，本文研究了国内外WPT的发展状况，介绍了磁耦合谐振式无线能量传输系统的结构组成和原理。因为在实际设计中经常因为频率分裂现象而不能高效传输电能，系统传输系数随距离变化起伏很大，为了改善上述问题，本文以收发线圈之间互感系数为纽带，对于不同半径的WPT/WRC的传输特性进行研究，并根据基本原理设计了相应的仿真电路模型。87570

其次，研究系统传输距离特性，保持线圈的电容、高度等参数一致，然后对线圈的半径进行改变，取得不同半径下的系统传输距离，并且可以得到理论临界距离以及相应的关系曲线。运用电磁仿真软件进行WPT/WRC系统电路模型的建立（SS型），对于给定半径的WPT/WRC系统的传输特性进行仿真探究。

最后，不断改变线圈半径，运用电磁仿真软件对于不同半径的WPT/WRC的传输特性进行仿真研究，并将仿真结果与理论研究进行对比分析。

Title Design and Research on WPT/WRC

Abstract First of all, the paper studies the development situation of WPT at home and abroad,The structure and operation principle of magnetically coupled resonant wireless power transmission system are introduced。In fact, because of the frequency splitting phenomenon ,the system usually cannot transmit the electricity efficiently, transmission system coefficient varies with distance fluctuated widely。In order to improve these problems, the mutual inductance between the transceiver coil become a link for the WPT transmission characteristics of different radii , and based on the basic principles of design corresponding simulation circuit model。

Next, the paper studies the system characteristics of the transmission distance, holding consistent winding of a capacitor, height and other parameters, and then changes the radius of the coil, and the critical distance and the corresponding theoretical curve can be obtained 。Then using electromagnetic simulation software to establish the circuit model of WPT / WRC for a given radius ,then explore the principle。

Finally,Changing radius of the coil, and using electromagnetic simulation software to analyze the transmission characteristics of different radii。And the simulation results were compared with the theoretical study。
