CONTROLLING WIRELESS POWER TRANSFER SYSTEMS
First Claim
1. A method of operating a wireless energy transfer system comprising:
- tuning, by a wireless energy transmitter, a transmitter impedance matching network (IMN) of the wireless energy transmitter to achieve a target transmitter power characteristic;
sending, by the wireless energy transmitter, power data that indicates the power of the transmitter to a wireless energy receiver;
tuning, by the wireless energy receiver and based on the power data, the receiver-IMN to improve an efficiency of the wireless energy transfer system.

Abstract
Methods, systems, and devices for operating wireless power transfer systems. One aspect features a wireless energy transfer system that includes a transmitter, and a receiver. The transmitter has a transmitter-IMN and is configured to perform operations including performing a first comparison between a characteristic of a power of the transmitter and a target power. Adjusting, based on the first comparison, a reactance of the transmitter-IMN to adjust the power of the transmitter. The receiver has a receiver-IMN and is configured to perform operations including determining an efficiency of the wireless energy transfer system at a second time based on power data from the transmitter. Performing a second comparison between the efficiency at the second time and an efficiency of the wireless energy transfer system at a first time, the first time being prior to the second time. Adjusting, based on the second comparison, a reactance of the receiver-IMN.
