WIRELESS POWER TRANSMITTING/RECEIVING SYSTEM COMPRISING TRANSMITTER AND RECEIVER, TWO-WAY COMMUNICATION METHOD BETWEEN THE TRANSMITTER AND THE RECEIVER, AND THE APPARATUSES

摘要

PURPOSE: A bidirectional communication method between a transmitter and a receiver in a wireless power transceiver system and devices thereof are provided to efficiently transceive wireless power by using bidirectional communication transmitter and receiver. CONSTITUTION: Turn-on power is transmitted to a receiver(200) through a Tx resonator according to the detection of the receiver. The transmission of wireless power is requested through a wireless communication module. An SID(short ID) and a time slot corresponding to the receiver is allocated. The SID and the time slot are transmitted to the receiver through the wireless communication module. Demand power is requested from the receiver through the wireless communication module. The impossibility of transmitting the demand power is notified to the receiver through the wireless communication module according to a comparison result.
