  • Passive magnetic field attenuation
    Patent number: 10530193
    Abstract: A first apparatus for passive magnetic field attenuation comprises a wireless power transfer (“WPT”) pad comprising one or more windings and a ferrite structure adjacent to the one or more windings, and a passive magnetic flux cancellation (“PMFC”) structure located adjacent to the WPT pad. The PMFC structure includes one or more vertical shields oriented substantially perpendicular to the WPT pad, where each of the one or more vertical shields attenuates an electromagnetic field, and a vertical shield retention structure that retains each of the one or more vertical shields in position with respect to the WPT pad.
    Type: Grant
