Abstract
A wireless power transfer system in which the driver and control circuitry are located within the electromagnetic field of the power transmission antenna, e.g., a charging coil. The power transfer system may be contained in a flexible housing, which change shape using one or more hinges, be formed of a conformable material and so on. Changes in the relative location of the antenna and the circuitry may cause interference in the circuitry and loading of the antenna, which in turn may impact the electromagnetic field output by the antenna. The wireless power system may include sensors that provide an indication of an amount of deformation of the system. The driver circuitry of this disclosure may receive an indication of the relative location of the circuitry to the antenna and compensate for changes in the output electromagnetic field caused by changes in the relative location.
