APPARATUS AND METHOD FOR CONTROLLING POWER IN A LOCAL COMMUNICAION AND WIRELESS POWER TRANSMISSION SYSTEM

摘要

PURPOSE: A power control apparatus and a method thereof are provided to perform the power control of wireless power transmission efficiency by securing necessary magnetic field communication capacity. CONSTITUTION: A transmission unit (100) performs power allocation when the efficiency of wireless power transmission is maximized. The transmission unit encodes and modulates transmission information. The transmission unit transmits a transmission signal and a transmission power. A reception unit (150) receives the transmission signal and the transmission power to a coil antenna. The reception unit stores the power. The reception unit restores the transmission information by modulating and decoding the transmission signal.
