PERFORMANCE COMPARISON BETWEEN CGC MODEL AND CLGC MODEL ON THE WPT SYSTEM 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. The derivation of the optimal coreless-type WPT model applied to either urban railway vehicles or high-speed railway vehicles is conducted in this study. The characteristic variations of the equivalent circuit parameters and the coupling coefficient k on each coreless-type WPT model are compared. In order to verify the characteristic analysis results from the simulation method of the coreless-type WPT model, two small-scaled proto-models are manufactured and tested for both the conventional core-type WPT model and the coreless-type model which has the best performance. It is confirmed that the coreless-type WPT model could have similar performance with the core-type WPT model through the performance tests.
