APPARATUS AND METHOD FOR PERFORMING DATA STREAM TRANSMISSION IN WIRELESS POWER TRANSFER SYSTEM

A wireless power transmitter includes a power conversion unit configured to transfer wireless power to a wireless power receiver by forming magnetic coupling with the wireless power receiver; and a communication/control unit configured to communicate with the wireless power receiver to control transmission of the wireless power and to perform high level data transport. Further, the communication/control unit is configured to transmit a data stream including a sequence of data packets in which the high level data is divided to the wireless power receiver based on the high level data transport, and the data stream includes at the beginning an auxiliary data control packet.
