A wireless power transmission apparatus for tracking a charging capacity of each of a plurality of wireless power reception apparatuses in an environment in which the plurality of wireless power reception apparatuses are charged includes a communication unit configured to receive information about either one or both of a charging support power and a requested power from each of the plurality of wireless power reception apparatuses, a controller configured to determine a charging capacity for a wireless power reception apparatus supporting the charging support power among the plurality of wireless power reception apparatuses based on the information about the charging support power, and a power tracker configured to re-track the determined charging capacity based on charging status information received from the plurality of wireless power reception apparatuses.

Wireless power transmission apparatus and method

A method of operating a wireless power transmission apparatus includes receiving, from a wireless power reception apparatus, information on an operating power of a micro control unit (MCU) of the wireless power reception apparatus and information on an output of a direct current-to-direct current (DC/DC) converter of the wireless power reception apparatus; determining whether a charging power is to be transmitted to the wireless power reception apparatus based on the received information on the output of DC/DC converter; and transmitting, to the wireless power reception apparatus, an MCU operating power calculated based on the received information on the operating power of the MCU in response to a determination that the charging power is not to be transmitted to the wireless power reception apparatus.

Method and apparatus for wirelessly transmitting power and power transmission information

A method of synchronization control of a power transmitting unit (PTU) includes network-connecting a PTU to a PTU operating in a slave mode by setting an operation mode of the PTU to a master mode, and transmitting a signal to a power receiving unit (PRU) by controlling either one or both of a communication time and a communication frequency of the PTU operating in the slave mode.

Method and apparatus for synchronization control in wireless power transmission system

A method of operating a wireless power transmission apparatus includes receiving information on rectifier output voltages from at least one wireless power reception apparatus; determining whether the rectifier output voltages are within a predetermined operating range, and controlling an impedance of the wireless power transmission apparatus based on a result of the determining.

Method of controlling impedance matching with respect to multiple targets in wireless power transmission system, and wireless power transmission system adopting the method

A method of configuring a network of a power transmitting unit (PTU) includes determining whether a neighboring PTU is operating in a master mode; determining an operation mode of a PTU based on a result of the determining; and setting a network between the PTU and the neighboring PTU based on the operation mode of the PTU.
