Title:
METHODS AND APPARATUS FOR TESTING OF WIRELESS POWER TRANSMITTERS AND SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2016/057674
Kind Code:
A3
Abstract:
This disclosure provides methods and apparatus for wireless power field testing. A method for generating testing the interoperability of a wireless power transmitter with one or more wireless power receivers is provided. The method includes generating a magnetic field via a transmit antenna. The method further includes measuring a first uniformity of the magnetic field at all the locations within the magnetic field on a charging surface of the wireless power transmitter. The method also includes determining that the measure first uniformity of the magnetic field is within a range of values at all locations on the charging surface of the wireless power transmitter. In some implementations, the method further includes applying a load to the magnetic field, measuring a second uniformity of the magnetic field while the load is applied, and determining if the first uniformity of the magnetic field is substantially similar to the second uniformity.
