CHARGING DEVICE THAT FOCUSES FLUX BY FLOWING CURRENT THROUGH SPIRALS IN OPPOSING RADIAL DIRECTIONS

CHARGING DEVICE THAT FOCUSES FLUX BY FLOWING CURRENT THROUGH SPIRALS IN OPPOSING RADIAL DIRECTIONS

Charging devices described herein include at least one coil having spirals through which current flows in opposing radial directions to focus flux. For instance, the flux for a coil may be focused in a shape of a toroid having first and second cross-sections that intersect the respective spirals of...

description Charging devices described herein include at least one coil having spirals through which current flows in opposing radial directions to focus flux. For instance, the flux for a coil may be focused in a shape of a toroid having first and second cross-sections that intersect the respective spirals of the coil at a plane in which the spirals are defined. Focusing the flux in this manner may facilitate wireless power transfer from the coil(s) to a chargeable wireless device.
