This paper explores the effect of the shielding plate in the inductive power transfer (IPT) pads, and identify its impact on leakage magnetic field and pads losses. The 3-D finite-element analysis method is used to optimize the structure of the shielding plate. The shielding effectiveness is investigated in terms of thickness of the shielding plate, air-gap distance between the shielding plate and the ferrite plate, covering area and geometry of the shielding plate. The result shows that the shielding structure plays dominant role in leakage magnetic field and pad losses. By using the optimized shielding structure, both the leakage magnetic field in the vicinity of the WPT system and the power loss in the transmission pads are reduced, which provides a reference of shielding structure design for IPT systems.
