Abstract:
A wireless power transmitter and a method for detecting a change in load during wireless charging in the wireless power transmitter is provided. The wireless power transmitter includes a power transmission unit configured to transmit power to a wireless power receiver, a current detection unit configured to measure a voltage value corresponding to a current that is output to the power transmission unit while the power is transmitted from the power transmission unit, and a controller configured to adjust the power transmitted by the power transmission unit based on the measured voltage value.
