APPARATUS FOR COMMUNICATION BETWEEN POWER SUPPLY AND PICKUP DEVICE BY MULTI-FREQUENCY MATCHING

摘要

PURPOSE: An intercommunication device using the multi-frequency band matching of a wireless power rapid progress line is provided to match the wireless power rapid progress line with a multi-frequency band and perform wireless communication between a feeding device and a collecting device by using the matched multi-frequency band. CONSTITUTION: A feeding device(200) includes a feeding coil(220), a feeding core(210), and a communication unit. A current flows in the feeding coil. The feeding core delivers a magnetic field generated by the currents of the coil to a collecting device(100). The communication unit performs wireless communication with the collecting device by using a resonant frequency band except for a wireless power transmission frequency between the feeding device and the collecting device.
