Method and power transmitter for controlling power transmission
First Claim
1. A method of controlling power transmission in a power transmitter, the method comprising:
- receiving, from at least one power receiver, a first message including a first voltage and a second voltage that is greater than the first voltage;
transmitting power to the at least one power receiver;
receiving, from the at least one power receiver, a second message including a third voltage measured at the at least one power receiver while transmitting the power; and
adjusting an amount of the power based on whether the third voltage is between the first voltage and the second voltage,wherein the first voltage is a minimum voltage for the at least one power receiver.

Abstract
Methods and apparatuses are provided for controlling power transmission in a power transmitter. A first message including a first voltage and a second voltage that is greater than the first voltage, is received from at least one power receiver. Power is transmitted to the at least one power receiver. A second message including a third voltage measured at the at least one power receiver during power transmission from the power transmitter, is received from the at least one power receiver. An amount of the power is adjusted based on whether the third voltage is between the first voltage and the second voltage. The first voltage is a minimum voltage for the at least one power receiver.

7. A power transmitter for controlling power transmission, the power transmitter comprising:
-
a resonator; a power supply; a wireless communication unit configured to receive, from at least one power receiver, a first message including a first voltage and a second voltage that is greater than the first voltage, and receive, from the at least one power receiver, a second message including a third voltage measured at the at least one power receiver while transmitting the power; and a controller configured to control the power supply to; transmit the power to the at least one power receiver through the resonator; and adjust an amount of the power based on whether the third voltage is between the first voltage and the second voltage, wherein the first voltage is a minimum voltage for the at least one power receiver. - View Dependent Claims (8, 9, 10, 11, 12)
