Abstract

This disclosure provides systems, methods and apparatus for wireless power transfer. In one aspect, an apparatus transfers energy wirelessly to at least one receive antenna of at least one receiver. The apparatus comprises a first antenna configured to generate a first wireless field when the at least one receiver is in an energy transfer region of the first transmit antenna. The apparatus further comprises a second antenna configured to generate a second wireless field when the at least one receiver is in an energy transfer region of the second transmit antenna. The apparatus further comprises a controller configured to activate at least one of the first antenna or the second antenna based on whether the at least one receiver is in an energy transfer region of one or both of the first and second wireless fields.

Description

technical field [0001] The present invention generally relates to wireless power. More specifically, the present invention is directed to transmitters and receivers in wireless power transfer systems. Background technique [0002] An increasing number and variety of electronic devices are powered via rechargeable batteries. Such devices include mobile phones, portable music players, laptop computers, tablet computers, computer peripherals, communication devices (eg, Bluetooth devices), digital cameras, hearing aids, and the like. While battery technology has improved, battery-powered electronic devices increasingly require and consume greater amounts of power, and thus often require recharging. Rechargeable devices are often charged via a wired connection via a cable or other similar connector that physically connects to a power supply. Cables and similar connectors can sometimes be inconvenient or cumbersome, among other disadvantages. A wireless charging system capable...
