Wireless power repeater and method thereof
First Claim
1. A wireless power repeater for relaying power transmission in which a wireless power receiver is disposed between a wireless power transmitter and the wireless power repeater, the wireless power repeater comprising:
- a position detector for detecting a position of the wireless power receiver;
a repeater resonator unit including a plurality of repeater resonators; and
a controller for operating one repeater resonator of the plurality of repeater resonators, which is located close to an extension line of the wireless power transmitter and the wireless power receiver, based on position information detected by the position detector;
wherein the controller controls switches provided in the repeater resonators, respectively, to operate the one repeater resonator of the plurality of repeater resonators, andwherein a coupling coefficient between the one repeater resonator of the plurality of repeater resonators and a transmission resonant coil of the wireless power transmitter is equal to or higher than a critical value.
