Abstract

A method for wireless power transmission includes establishing respective wireless communication link between a coordinating transmitter and each receiver. The method further includes measuring respective mutual impedance between a coordinating transmitter and each receiver by applying a voltage to the coordinating transmitter and configuring each receiver to measure an induced current in response to the applied voltage. The method calculates respective matching impedance for the coordinating transmitter and each receiver based on corresponding mutual impedance. The method transmits the respective matching impedance to each receiver to enable each receiver to adjust to have the respective matching impedance. The method adjusts the coordinating transmitter to have the respective matching impedance.

Description

technical field [0001] The present disclosure relates to a wireless power transfer network using magnetic resonance, and more particularly, to a wireless power transfer network with a wireless communication link between devices for sharing information in order to improve optimal power transfer efficiency. Background technique [0002] Wireless power transfer to electronic devices, also known as wireless energy transfer or wireless charging, is an area that is attracting increasing attention. In a wireless power transfer network consisting of multiple devices such as transmitters, receivers, and transponders, one challenge is the impedance adjustment of the devices to achieve improved power transfer efficiency. Contents of the invention [0003] A method for wireless power transfer includes establishing a corresponding wireless communication link between cooperating transmitters and each receiver. The method includes measuring respective mutual impedances between the coope...
