| Zusammenfassung: | A cooking apparatus includes: a working coil, an inverter including a plurality of switching elements and configured to apply, by operating the plurality of switching elements, a resonant current of a predetermined frequency to the working coil, a phase detector configured to detect a phase difference between the resonant current and a voltage applied to an output terminal of the inverter, and a controller configured to calculate, based on the detected phase difference, a temperature of a target object that is placed above the working coil. |
