摘要
In this article, a dual-loop active shielding coil directly connected in series with the primary coil is proposed to reduce the leakage magnetic field while eliminating the additional coupling between the shielding coil and the receiving coil of a wireless electric vehicle (EV) charging system. Parameter design strategy featuring system efficiency improvement and shielding coil cost reduction using multi-objective optimization algorithm is proposed. Finally, a 1.5 kW with 19 cm air gap prototype is fabricated to verify the analytical results and investigate the influence of the shielding coil over the system parameters. The results prove that the proposed active shielding coil shows its advantage on the system transmission performance and the shielding effectiveness on the target surface comparing to conventional aluminum shielding.
