Wireless charger for charging control and charging control method therefor

A wireless charger for charging control, including a primary coil for performing charging through a secondary coil included in a charging target, the wireless charger comprising:

• a plurality of flat spiral concentric coils having different radii;
• a touch pad provided on one surface of the wireless charger;
• a location sensor included in the touch pad, for sensing whether the charging target is placed on the touch pad and providing information about a location where the charging target is placed;
• a controller for selecting a coil to be activated among the plurality of coils according the location information provided by the location sensor;
• and
• a power determiner for determining power to be applied to the selected coil and supplying the determined power to the selected coil,
• wherein the plurality of flat spiral concentric coils having different radii have smaller numbers of turns as the radii thereof increase so as to generate the same inductance among the plurality of flat spiral concentric coils.
