WIRELESS POWER TRANSMITTER AND POWER TRANSMISSION METHOD THEREOF
First Claim
1. A wireless power transmitter for wirelessly transmitting power to a wireless power receiver by using resonance, the wireless power transmitter comprising:
- a plurality of transmission resonance units;
a detection power applying unit applying detection power to the transmission resonance units to detect a location of the wireless power receiver; and
a current measuring unit measuring current generating from an inner part of the wireless power transmitter based on the applied detection power,wherein the wireless power transmitter transmits the power through at least one transmitting resonance unit corresponding to the location of the wireless power receiver based on the measured current.
