Study of Sliding Transformer in Contactless Power Transfer System

Sliding transformer is a core element in contact-less inductive power transfer system of automatic dock,which can realize safe power supply for highspeed freight dollies.The state-space mathematical model of sliding transformer is set up for its features of longer air gap and larger leakage flux on the basis of coupled inductor theory,and also its simulation model is established on the base of the popular software Matlab/Simulink.The simplicity of the model parameters are convenient for use.The effectiveness of the model is validated by comparison and analysis of various compensation topologies and resonant frequency of the power transfer system,and a reliable basis is provided to select compensation scheme and operating frequency for the system.
