Abstract
Disclosed is a wireless power transmitter. A wireless power transmitter includes a transmission coil for generating a magnetic field by receiving power from a power source, a transmission resonant coil for transmitting power to a receiving coil by using the magnetic field generated from the transmission coil by using resonance, a detection unit for detecting an approach of the receiving coil and a power regulator for adjusting an output of the power source, which supplies the power, based on the approach of the receiving coil detected by the detection unit.
