APPARATUS AND METHOD FOR CONTROLLING WIRELESS POWER TRANSMISSION

摘要

PURPOSE: A radio charging device and a method thereof are provided to simplify circuit configuration by connecting components for near field communications to one another via connection terminals. CONSTITUTION: A contactless near field radio communication part (112) performs contactless near field radio communication operations for a radio power transmitter and radio charging and performs radio charging certification via a contacless near field radio communication antenna. A radio power receiving part (126) receives the power from the radio power transmitter by using a resonator which resonates with the same resonance frequencies as the radio power transmitter according as the radio charging certification is performed. A charging controller (114) performs the radio charging by using the power received by the radio power receiving part. Switches (111,121) perform switching operations with the contactless near field radio communication antenna, the radio power receiving part and the charging controller.
