Abstract :
This paper deals with the magnetic shielding of the field generated by a wireless power transfer (WPT) system at the frequency of 20 kHz. Different shielding techniques are examined and discussed based on the use of conductive and magnetic material panels. The performances of the WPT system and the magnetic field shielding effectiveness (SE) in presence and in absence of shield panels are calculated and measured.
