A study on the Wireless Power Transfer Module with Coreless-type Ground Coil for Railway Transit

초록

This paper presents the derivation and investigation of a practical model structure for the large-capacity WPT system capable of powering to railway system. Comparative analyses of the secondary pickup induced voltages and rail induced voltages for various WPT models are conducted to derivate the optimal WPT model which could be applied to railway vehicles. Through the analyses for various WPT models, a coreless-type WPT model structure, which has the same dimension and performance as the secondary pickup module of the conventional core-type WPT model, is derived.
