Abstract

A contactless power transmission system work based on high-frequency electromagnetic induction, companying amount of leakage magnetic flux spread outside the coupling structure and inducing power loss in the metal shell. It is necessary to design shielding mechanism to weaken the influence of leakage magnetic flux. This paper analyzed the shielding effectiveness of metal layer in the time-varying change magnetic field, and revealed the shielding function of a thin copper sheet between cores and shells. By using FEM simulation, distributions of magnetic intensity and eddy current density were imaged and compared to demonstrate the shielding effectiveness. Finally, a prototype of coupling structure with shielding sheets was proposed and tested. The testing results proved the significant affection of shielding sheet on improving the system’s transferring ability.
