Abstract

The resonant coils are the significant part of the whole wireless power transfer system. The magnetic field leakage will cause the human exposure to time-varying electromagnetic fields problems and low coupling coefficient. In this paper, a 3D model is established to simulate the magnetic field. A new shielded structure is proposed in this paper. A comparasion of the magnetic field between shielded structure and unshielded structure is presented in this paper. An experiment of 8kw and 10kw wireless power transfer system are established in this paper. And as the results of simulation and experiment, the new shielded structure achieve the higher coupling coefficient and suppress the magnetic field leakage.
