Research on the Coupling Coefficient of the Wireless Power Transmission System

Abstract:

The simulation model of wireless power transmission system is based on the experimental model contained E-E-sized core. Analyzing the basic electro-magnetic relation of loosely coupled transformer in the WPT system ,and studying the principle of the energy method to calculate the inductances and coupling coefficient. Using the finite element simulation software to analyze the inductances and coupling coefficient of different air gap, transverse lateral distance and longitudinal lateral distance, finding the effect of the coupling coefficient by the above three situations, which provide a reference for improving the coupling coefficient and efficiency of the wireless power transmission system.
