Abstract
An induction heating device and a method for sensing a cooking vessel on an induction heating device are provided. The induction heating device may include a controller that converts a resonance waveform generated as current is applied to a sensing coil into a square waveform. The controller may determine whether a cooking vessel placed on the induction heating device has an inductive heating property based on a number of pulses of the converted square waveform.
