摘　　要：无线电能传输技术是一种通过电磁效应或者能量交换作用实现从电源到负载无电气接触地进行电能传输的新型输电方式,相比传统导线输电方式,其具有安全可靠等优点,尤其适用于一些特殊的应用场合,因此受到了越来越广泛的关注。在目前已有的无线电能传输技术中,研究较多的主要有磁场耦合式和电磁辐射式,其中磁场耦合式以磁感应耦合式和磁耦合谐振式为主,电磁辐射式以微波辐射式和激光方式为主。该文首先叙述了这4种主流无线电能传输技术的基本结构和工作原理,并对它们进行对比分析。然后,分别对4种主流无线电能传输技术的研究现状和待研究的关键问题进行分析,并总结了这些技术在一些重要领域的应用研究,如交通运输、医疗电子、消费电子和空间太阳能等领域。最后讨论无线电能传输技术的应用前景与发展趋势。The wireless power transmission technology is a new power transmission technology, which achieved power transmission without electrical contact from the power supply to the load by electromagnetic effect or energy exchange function. Comparing with the traditional wire transmission technology, it has advantages of safety and reliability and so on, especially in some special applications. Therefore, it has been more and more attention. In the current existing wireless power transmission technology, the magnetic field coupling and electromagnetic radiation technology is mainly proposed and discussed. The magnetic field coupling technology includes the inductive coupled and magnetically-coupled resonant type mainly, and the electromagnetic radiation technology includes the microwave radiation and laser emission type. The basic structure and working principle of these four main wireless power transmission techniques are summarized, and the analysis and comparison of these four techniques are carried firstly. And then the research status of key technology and the critical issues which remain to be solved of the four main wireless power transmission techniques are analyzed, and the application of these techniques in some important field, such as transportation, medical electronics, consumer electronics and space solar power and so on, are summarized. Finally, the application prospect and development trend of wireless power transmission technology is discussed.
