WIRELESS POWER TRANSMISSION APPARATUS AND METHOD THEREFOR
First Claim
1. A wireless power transmitter comprising:
- a power transmitting module configured to transmit wireless power using one of a magnetic field of first frequency band and a magnetic field of second frequency band that is different from the first frequency band;
a first communication module;
a second communication module; and
a controller configured to;
transmit a first magnetic field signal of the first frequency band through the power transmitting module;
detect a first response signal regarding the first magnetic field signal through the first communication module;
in response to receipt of the first response signal, search for a first wireless power receiver that transmits and receives wireless power using the first frequency band;
transmit the second magnetic field signal through the power transmitting module;
detect a second response signal regarding the second magnetic field signal through the second communication module; and
in response to receipt of the second response signal, search for a second wireless power receiver that transmits and receives wireless power using the second frequency band.
