摘　　要：无线电能传输(WPT)技术应用于轨道交通领域,可解决传统接触式供电在安全性、可靠性和经济性等方面的问题。但相比于当前主流WPT研究,该应用场景所涉及的功率大、系统复杂、实现难度较高,且在运动、机械等方面亦具有自身特征,存在诸多关键技术问题有待解决。该文从拓扑架构、磁耦合机构、系统建模与参数优化、控制策略等方面对其开展研究,取得了若干阶段性成果,并基于此研发350kW轨道交通无线充电系统样机,在功率传输能力、系统效率、输出特性等方面均取得了较好的效果。该文将从这一系统入手,对大功率轨道交通WPT的关键技术和实现方案进行阐述和探讨,力求为大功率WPT技术的发展及其在轨道交通中的应用提供助力。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.
