Abstract
An apparatus and a method for controlling the power transfer coverage of a wireless power transmission network are disclosed. The method for controlling the power transfer coverage of a wireless power transmission network, which includes a plurality of peripheral devices for receiving power from a main device through a resonant channel within the power transfer coverage of the main device, comprises the steps of: checking a wireless power transmission network disconnection state of any one of the plurality of peripheral devices by a procedure gradually decreasing the amount of transmission power of the main device; and forming the power transfer coverage on the basis of the amount of transmission power at the moment of the wireless power transmission network disconnection.
