Transmitter for wireless charging power transmission, and method and system for connection between internet of things system and wireless charging receiver

摘要

A transmitter for wireless charging power transmission comprises a transmitter-side power converting unit converting power of an input Alternating Current (AC) signal and outputting the converted AC signal; a transmitter-side resonant circuit unit generating a magnetic field based on the converted AC signal and providing power to a receiver located within a charging area; and a transmitter-side processor controlling power conversion of the transmitter-side power converting unit and performing impedance matching of the transmitter-side resonant circuit unit. The transmitter-side processor detects an object located within the charging area, generate a wireless power signal and output the generated wireless power signal to the transmitter-side power converting unit, recognizes the object as a receiver if modulation of the wireless power signal associated with the object is detected, receives identification information of the receiver, connects to the receiver for wireless charging power transmission based on charging authentication information included in the identification information, transmits IoT authentication information included in the identification information to an IoT system to enable the receiver to subscribe to the IoT system, and transmits wireless charging power to the receiver.
