摘　　要：磁悬浮非接触式供电是一种将磁悬浮与无线传能相结合的技术,利用地面线圈与车载次级线圈之间的电磁耦合实现电能传输。无论是应用于超导电动悬浮的直线发电机供电系统还是应用于电磁悬浮的感应式功率传输系统,都实现了列车运行时的非接触式供电,避免了接触式供电磨损、噪音以及气候敏感性、运行速度受限等问题。非接触式供电适用于不同类型的磁悬浮系统,有利于磁悬浮技术的进一步商业化发展。为此,重点介绍了磁悬浮非接触式供电的国内外发展状况及其进一步应用面临的挑战。Maglev non-contact power supply is a technology combining maglev and wireless power transmission,in which the electromagnetic coupling between the ground coil and onboard secondary coil is used to realize power transmission.Both the linear generator power supply system applied in superconducting electrodynamic suspension and the inductive power transmission system applied in electromagnetic suspension have realized non-contact power supply during the operation of trains,thereby avoiding the problems of contact power supply such as wear,noise,climate sensitivity and limited operating speed.As a result,non-contact power supply is suitable for different types of maglev system,which is conductive to the further commercial development of the maglev technology.In this paper,the domestic and overseas development of maglev non-contact power supply is introduced in detail,and the challenges facing its applications are also discussed.
