METHOD AND APPARATUS FOR CONTROLLING WIRELESS POWER TRANSMISSION AND RECEPTION, AND WIRELESS POWER TRANSMISSION SYSTEM

摘要

PURPOSE: A wireless power transmission system and wireless power transmission and reception control method are provided to effectively transfer voltage to a wireless power reception apparatus. CONSTITUTION: A control unit(820) selects one source resonant unit based on a coupling factor for each target apparatus or on power transferred to a plurality of target apparatuses. Each source resonant unit is contiguous to each apparatus. A power transmission unit(830) wirelessly transmits power to the target apparatus using magnetic coupling between the selected source resonant unit and a target resonant apparatus according to the control unit. The target apparatus is contiguous to the selected source resonant unit.
