发明名称 METHOD AND APPARATUS FOR WIRELESS POWER TRANSMISSION
摘要 Embodiments of the invention relate to a method and system for transferring power wirelessly to electronic devices. The system can utilize magnetic coupling between two coils at close proximity to transfer sufficient power to charge an electronic device. Embodiments of the invention pertain to an array of spiral coils that can be used to transmit power for transfer to receiver coils. Potential applications of this technology include charging consumer electronic devices (cell phones, laptops, PDAs, etc), developing hermetically sealed devices for extreme environments, and less invasive transcutaneous energy transfer (TET) systems. Various embodiments of the subject system can be referred to as PowerPad system. Embodiments can incorporate one or more of the following: planar inductors, PCB transformers, and very high frequency power supplies. Embodiments of the invention also pertain to planar inductors having characteristics that allow the production of even magnetic field, as well as systems that incorporate such planar inductors.

主权项 1. A system for transmitting power comprising: a first planar array of resonant coils configured to transmit power via a magnetic field for charging one or more portable electronic devices having a receiver, the array comprising at least two regions with each region including plural coils, wherein the regions are configured to be selectively activated or deactivated; and a controller electrically connected to the regions, the controller configured to selectively activate or deactivate one of the at least two regions in response to the presence of a receiver in the magnetic field area associated with the one region.
