Systems, apparatus and method for adaptive wireless power transfer
First Claim
1. An apparatus for wirelessly receiving power from a wireless power transmitter, the apparatus comprising:
- an active switching rectifier operably connected to a coupler and configured to operate in a first bridge mode and a second bridge mode; and
a controller configured to;
adjust an input resistance of the rectifier to a first value that provides a first wireless power transfer efficiency in response to configuring the rectifier in the first bridge mode, andadjust the input resistance of the rectifier to a second value that provides a second wireless power transfer efficiency less than the first wireless power transfer efficiency while operating within one or more operating limitations in response to configuring the rectifier in the second bridge mode.

Abstract
An apparatus for wirelessly receiving power from a wireless power transmitter is provided. The apparatus comprises an active switching rectifier operably connected to a coupler and configured to operate in a first bridge mode and a second bridge mode. The apparatus comprises a controller configured to adjust an input resistance of the rectifier to a first value that provides a first wireless power transfer efficiency when the rectifier operates in the first bridge mode. The controller is configured to adjust the input resistance of the rectifier to a second value that provides a second wireless power transfer efficiency less than the first wireless power transfer efficiency while operating within one or more operating limitations when the rectifier operates in the second bridge mode.
