METHOD FOR DETECTING LOAD IN WIRELESS POWER NETWORK AND WIRELESS POWER TRANSMITTER

摘要

Various embodiments of the present invention relate to a method for detecting a load in wireless charging and a wireless power transmitter. According to an embodiment, a wireless power transmitter may include a power transmitting part which transmits power to a wireless power receiver; a current detection part which measures a voltage value corresponding to a current outputted to the wireless power transmitting part while the power is transmitted to the power transmitting part; and a control part which controls power transmitted to the power transmitting part based on the measured voltage value. Various embodiments can be provided. So, a current outputted to a resonator can be detected.
