Abstract
A coil structure and a charging control method in a wireless charger having a primary coil are provided to supply an induced electromotive force suitable for a charging target having a secondary coil. Concentric coils having different radii are arranged in a wireless charger, and a coil suitable for the location of a charging target placed on the wireless charger is selected. An input power corresponding to the selected coil is determined, and the determined power is applied to the selected coil. Then the same charging efficiency can be provided irrespective of a location of a charging target placed on the wireless charger.
