Abstract:The application of wireless power transfer (WPT) technology in the rail transit field can solve the problems of traditional contact power supply in terms of safety, reliability and economy. However, compared with the current mainstream WPT research, the power requirement is much higher and the system is much more complex for this application, which causes higher difficulty to implementation. Moreover, it also has specific characteristics in motion and machinery. Therefore, there are many key technical issues to be solved. In this paper, it has been studied from the aspects of the topology architecture, magnetic coupling mechanism, system modeling and parameter optimization, and control strategy, etc. Several phased results have been obtained, and accordingly a prototype of 350kW wireless charging system for rail transit has been developed, thereby achieving good effects in terms of power capability, efficiency and output characteristics. The key technologies and implementation schemes are expounded and discussed based on this system to promote the development of high power WPT technology and its application in rail transit.
