WIRELESS POWER SUPPLY DEVICE, ELECTRONIC DEVICE CAPABLE OF RECEIVING WIRELESS POWER, AND METHOD FOR CONTROLLING TRANSMISSION OF WIRELESS POWER

摘要

PURPOSE: A wireless power supply device, an electronic device capable of wirelessly receiving power, and a wireless power transmission control method are provided to efficiently use power with low costs by efficiently controlling the power when the power is wirelessly supplied. CONSTITUTION: A communication unit (480) receives power information including one of power rates information and power demand information. A wireless power receiving unit (430) receives wireless power which is wirelessly supplied from a wireless power supply device. A power converting unit (440) converts the received wireless power to power which is used for a corresponding electronic device. A control unit (460) controls an external wireless power supply device to request the transmission of the wireless power through the communication unit. An auxiliary power supply unit (420) provides the minimum auxiliary power for the corresponding electronic device.
