DEVICE AND METHOD FOR SELECTIVELY CONTROLLING MULTIPLE TRANSMISSION COILS IN WIRELESS POWER TRANSMISSION DEVICE
First Claim
1. A method for selectively controlling a plurality of power transmission coils in a wireless power transmission device, comprising:
- outputting a first detection signal and a second detection signal to a wireless power receiving device through a first power transmission coil and a second power transmission coil, respectively;
detecting either or both of a first response signal and a second response signal generated from the wireless power transmission device respectively in response to the first detecting signal and the second detecting signal;
selecting one of the first and second power transmission coils that corresponds to the detected one of the first and second response signals if only one of the first and the second response signals is detected;
selecting one of the first and second power transmission coils if both of the first and second response signals are detected; and
outputting a wireless power signal via the selected one of the first and second power transmission coil.
