WIRELESS POWER TRANSMISSION AND CHARGING SYSTEM, POWER CONTROL AND COMMUNICATION METHOD OF WIRELESS POWER TRANSMISSION AND CHARGING SYSTEM

摘要

PURPOSE: A wireless power transmitting/charging system and a communication and power control method of a wireless power transmitting/charging system are provided to prevent power waste of a source device by transmitting power in a specific condition. CONSTITUTION: A multiple source environment includes multiple source devices(211,221). A power deliver area(210) of the source device 1 is set up in order not to be overlapped with a power deliver domain(220) of a source device 2. A target device 1(213) and a target device 2(215) are located within the power transmission domain of the source device 1. A target device 3(223) is located within the power transmission domain of the source device 2. A target resonator of the target device 3 receives wake-up power activating a communication and control function from the source device 2. [Reference numerals] (AA) Voltage transmitter
