Abstract: Disclosed is a method of determining a magnetic resonant condition for a multi-device wireless power transfer system. A magnetic resonant condition determining method may determine a resonant condition based on a charge state, for example, a number of charging devices and a relative position between charging devices, for a multi-transmitter/receiver of a wireless power transfer system.
