WIRELESS POWER TRANSMISSION SYSTEM CAPABLE OF USING AN IN-BAND COMMUNICATION METHOD AND A POWER CONTROL METHOD THEREOF BASED ON A DETECTION PARAMETER

摘要

PURPOSE: A wireless power transmission system and a power control method thereof based on a detection parameter are provided to reduce interference about peripherals and increase power transmission efficiency.;CONSTITUTION: A power converter(118) generates wake-up electricity or operation electricity by converting a DC voltage into an AC voltage by using a resonance frequency. A source resonator(131) transmits wake-up electricity or operation electricity to a target device(120) through a magnetic coupling. A control and communication unit(117) transmits a wake-up request signal for an initial communication to the target device and receives the response signal of the wake-up request signal from the target device. The control and communication unit controls the power converter based on a detection parameter of target device which is included in the response signal.;COPYRIGHT KIPO 2013
