Abstract:
A wireless power transmission apparatus for induction heating includes: a working coil that is configured to change operation based on selection of a mode of operation from among a plurality of operating modes, the plurality of operating modes including a wireless power transmission mode configured to wirelessly transmit power and a heating mode configured to heat one or more objects, an inverter that is configured to output, to the working coil, current at an operation frequency, and a controller. The controller is configured to calculate an eccentricity degree between the working coil and a reception coil of a target object and control, in the wireless power transmission mode, the operation frequency based on the calculated eccentricity degree in a preparation period prior to wireless power transmission to the target object.
