Abstract 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 safe and reliable and so on, especially in some particular applications. Therefore, it has been more and more attention. Based on the existing research and review, this paper reviews the current research status and application of the four widely used WPT technologies in the near-field coupling and far-field radiation. The near-field coupling technology includes the inductive coupled and magnetically- coupled resonant type mainly, and the far-field radiation technology include the microwave radiation and laser emission type. In this paper, 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 out firstly. And then the research status of key technology and the critical issues which remain to the solved of the four main wireless power transmission techniques are analyzed, and the application of these techniques in any relevant field, such as transportation, medical electronics, consumer electronics and space solar power and so on, is summarized. Finally, the application prospects and development trend of wireless power transmission technology are discussed.
