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, voltage information required by the at least one power receiver, wherein the voltage information includes a minimum voltage, a reference voltage that is greater than the minimum voltage, and a demanded voltage;
transmitting power to the at least one power receiver;
receiving, from the at least one power receiver, a report about a power reception condition while transmitting the power, wherein the report includes a measured voltage at the at least one power receiver; and
adjusting an amount of the power based on whether the measured voltage is between the minimum voltage and the reference voltage.

Abstract
Methods and apparatus are provided for controlling power transmission. A minimum voltage and a maximum voltage receivable at the at least one power receiver, a reference voltage used to divide a range between the minimum voltage and the maximum voltage, and a demanded voltage required by the at least one power receiver, are received from at least one power receiver. A report about a power reception condition is received from the at least one power receiver. The report includes a measured voltage at the at least one power receiver during power transmission from the power transmitter. It is determined whether the measured voltage is between the minimum voltage and the reference voltage. Power is adjusted and supplied when the measured voltage is not between the minimum voltage and the reference voltage.

10. 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, voltage information required by the at least one power receiver, wherein the voltage information includes a minimum voltage, a reference voltage that is greater than the minimum voltage, and a demanded voltage, and to receive, from the at least one power receiver, a report about a power reception condition while transmitting power, wherein the report includes a measured voltage at the at least one power receiver; 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 measured voltage is between the minimum voltage and the reference voltage. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
