Abstract :
Contactless power transfer (CPT) system is widely used in high power recently. The characteristics of contactless transformer in CPT system have powerful influences on the performance of whole system. This paper studies the performance on movable loosely coupled transformer (MLCT) for CPT system, which can be used in rail transit system. Making use of 3D finite element methods, this paper investigates how much influence on MLCT produced by metal units in urban railway system, including the fixing units on the vehicle and the metal units on the ground. The results of such studies have great practical significance when the CPT system applied to urban railway system.
