Application Research of New Contactless Power Supply System for Medium Speed Maglev Train

The current power supply system is an indispensable part of maglev train, which mainly provides the electric energy needed by the on-board equipment of the train. The traction system of the medium speed maglev train with permanent magnet synchronous intermediate drive is transferred to the ground, and the electric energy required for traction is provided by the ground equipment. The current power supply system of maglev train should consider the actual operating environment of the train to provide the current service for the train. This article introduces a new contactless power supply system for medium speed maglev train And it describes the composition, control principle, performance parameters of main components and typical test. The system combines redundancy technology, mobile inductive coupling power transmission technology, and adopts modular design. The system has been developed for the first time on the maglev train and test line.
