Abstract
A cooking apparatus includes an upper plate configured to support a cooking vessel, a heating module that is movably disposed in a space under the upper plate and that includes a coil, a substrate that is disposed between the upper plate and the heating module and that includes a plurality of coil patterns, an inverter configured to supply a resonance current to each of the plurality of coil patterns, and a controller configured to control the heating module, the substrate, and the inverter. The controller determines a position of the cooking vessel on the upper plate based on the number or a frequency of pulses of resonance current supplied to each of the plurality of coil patterns. The cooking apparatus recognizes the position of the cooking vessel disposed on the cooking apparatus and moves the heating module to the recognized position.
