The shielding technique by active coils is proposed to mitigate the magnetic field produced by a dynamic wireless power transfer (WPT) system for wireless recharging the batteries of in motion electrical vehicles (EVs). Active planar coils mounted in an electrified road with multiple-pads architecture are proposed. The active coils are adequately powered so that the field in surrounding of the electrified road is compliant with reference levels (RLs) of ICNIRP 2010 guideline. The influence of the active shielding system on the performance of the WPT system is also investigated.

Abstract
The shielding technique by active coils is proposed to mitigate the magnetic field produced by a dynamic wireless power transfer (WPT) system for wireless recharging the batteries of in motion electrical vehicles (EVs). Active planar coils mounted in an electrified road with multiple-pads architecture are proposed. The active coils are adequately powered so that the field in surrounding of the electrified road is compliant with reference levels (RLs) of ICNIRP 2010 guideline. The influence of the active shielding system on the performance of the WPT system is also investigated.File in questo prodotto:
