摘要随着电子产品的快速发展，越来越多的电源连接线开始困扰人们的生活，而电磁谐振耦合无线电能传输技术正可以很好解决对距离有较高要求的这类问题。电磁谐振耦合无线电能传输技术是近几年刚被提出的无线电能传输技术，它依靠近电磁场中近区场和谐振线圈的强耦合实现了电能的中程距离的高效传输。它改善了传统无线电能传输中技术中距离跟效率之间的不足，具有重要的研究价值和广阔的应用前景。在比较了多种拓扑结构和控制方法后，选定了半桥逆变为主拓扑控制方式，芯片SG3525为控制芯片，原边采用串联补偿，副边采用并联补偿，驱动方式为图腾柱结构。然后本文对这种控制方式的原理，存在的问题进行深刻的研究。在本设计中进行了实物设计，经测试表明，设计满足要求。关键词：电磁谐振耦合，无线电能传输，半桥逆变AbstractWith the rapid development of electronic products, more and more power cablebegan to plague the lives of people, the electromagnetic resonant coupling wireless powertransmission technology can solve this problem of higher requirements is the distance. Theelectromagnetic resonant coupling wireless transmission technology is a new type ofwireless transmission technology, which utilizes non-radiated magnetic field of the nearfield coupling and the resonance principle to realize the distance to the mid-range andeffective transfer of electrical energy. It overcomes the disadvantages of traditionalwireless power transfer and has important research value and broad application prospects.After the comparison of the various topologies and control methods, selected the half bridge inverter topology control ways, SG3525 chip as the control chip, the original edge with series compensation, vice side of the parallel compensation, drive mode for the totem pole structure. Then this paper the principle of this control mode, existing problems are studied deeply. Physical design was carried out in this design, the test showed that the design meet the requirements.Keywords: Magnetic coupling resonant, Radio can transmit, half bridgeinverter topology目录第1章绪论11.1课题研究的意义11.2无线电能传输方式21.3国内外发展状况3第2章总系统设计52.1设计任务与要求52.2设计任务分析62.3设计任务总体框图8第3章方案选择93.1发射电路选择103.2 MOSFET选择143.3接收电路选择153.4接收电路器件选择183.5 控制电路选择183.6 驱动电路选择243.6.1磁的基本概念253.6.2 驱动变压器283.7谐振方式选择333.8 谐振电感和电容选择37第4章电路测试404.1波形分析404.2实验结果44结论45致谢46参考文献47ContentsChapter 1 Introduction.................................................................................11.1 The significance of the researc
