Abstract
Disclosed is a device configured to inductively heat one or more objects and to wirelessly transfer power to one or more objects. The device includes a first working coil, an inverter unit configured to cause a resonant current to flow in the first working coil by performing a switching operation, a first detection unit connected to the first working coil and configured to detect the resonant current applied to the first working coil, and a control unit configured to: determine whether a target object is located at a location corresponding to the first working coil by controlling operation of the inverter unit and the first detection unit; or to control output of the first working coil.
