System and method for reducing leakage flux in wireless electric vehicle charging systems
Abstract:
A method and apparatus for reducing leakage magnetic flux in wireless vehicle charging systems are disclosed. A wireless power receiver may be configured to couple to a wireless field generated by a wireless power transmitter. A portion of the wireless field may comprise the leakage magnetic flux. A leakage collector comprising a ferromagnetic material may be positioned at a distance from the wireless power receiver within the wireless field and may be configured to absorb or redirect at least a portion of the leakage magnetic flux away from an outer edge of an electric vehicle.
