Devices and methods for controlling transmitter power supply based on wireless receiver request
First Claim
1. A wireless power receiver, comprising:
- a power receiver circuit configured to receive power from a wireless power transmitter at a level sufficient to power or charge a load; and
a processor circuit configured to adjust a level of current being provided to the load based on a change in a level of received power to be requested to the wireless power transmitter, and send to the wireless power transmitter the request to change a present current level of the received power to a first different level.

Abstract
Devices and methods for controlling a power supply of a wireless power transmitter based on the request of a wireless power receiver are disclosed. One embodiment provides a wireless power receiver. The wireless power receiver includes a power receiver circuit configured to receive power from a wireless power transmitter at a level sufficient to power or charge a load. The wireless power receiver also includes a processor circuit configured to adjust a level of the received power being provided to the load based on a change in a level of received power to be requested to the wireless power transmitter. The processor circuit is further configured send to the wireless power transmitter the request to change the level of the received power to a first different level.

14. A method of receiving wireless power, comprising:
-
wirelessly receiving power from a transmitter at a level sufficient to power or charge a load; providing the received power to the load; comparing the level of the received power with a threshold power value; adjusting a level of current being provided to the load based at least in part on the comparison; and sending to the transmitter a request to change the level of the received power to a different power level subsequent to the adjusting the level of the current. - View Dependent Claims (15, 16, 17, 18)
