    Abstract: A method for controlling an abnormal state of a wireless Power Receiving Unit (PRU) is provided. The method includes measuring a temperature by a period shorter than a previous measurement period when a temperature measured by the wireless PRU in response to a transmission of power from a wireless Power Transmitting Unit (PTU) is higher than a temperature required to be monitored; determining whether the measured temperature is higher than a temperature at which a load switch connected to a charging unit is turned off if the measured temperature is equal to or higher than the temperature required to be monitored; and turning off the load switch if the measured temperature is higher than the temperature at which the load switch is turned off.

    Abstract: Methods and apparatuses are provided for controlling power transmission in a power transmitter. Voltage information including a minimum voltage, a maximum voltage, and a first voltage, is received from each of a plurality of power receivers. Power is transmitted to the plurality of power receivers based on the voltage information. A respective report about a power reception condition is received from each of the plurality of power receivers while transmitting the power. Each respective report includes a measured voltage at a corresponding power receiver of the plurality of power receivers. A power receiver is selected from among the plurality of power receivers based on the received reports. An amount of the power is adjusted by reducing a difference between a first voltage of the selected power receiver and a measured voltage of the selected power receiver.

    Abstract: A method and power transmitter for efficiently controlling power transmission to one or more power receivers in a wireless multi-power transmission system are provided. The method includes performing, when a predetermined measurement cycle arrives, a load measurement; comparing a current load measurement value with a previous load measurement value; determining whether the current load measurement value is increased over the previous load measurement value by at least as much as a first predetermined threshold; gradually increasing, when the load measurement value is increased over the previous load measurement value by at least as much as the first threshold, a transmission power value until a request for a subscription to a wireless multi-power transmission network from a power reception target within a predetermined time limit; and stopping, when the request for the subscription is not received before the time limit is exceeded, power transmission to the power reception target.
