Abstract
A method for generating a load variation for detecting a wireless power receiving unit in wireless charging is provided. The method includes maintaining a switch connected to a dummy load in an ON state by the wireless power receiving unit, receiving wireless power from a wireless power transmitting unit, and, upon receiving the wireless power, switching the switch connected to the dummy load to an OFF state.
