WIRELESS POWER TRANSMITTER AND WIRELESS POWER TRANSMISSION METHOD
First Claim
1. A wireless power transmitter which wirelessly transmits a power to a wireless power receiver, the wireless power transmitter comprising:
- a transmission coil for wireless transmitting a power;
a power source for supplying the power to the transmission coil; and
a detector for detecting an intensity of current output from the power source,wherein the power source supplies the power at a predetermined period through a time-division scheme to determine an existence state of the wireless power receiver.
