Abstract
A method for controlling an induction heating cooking apparatus, comprises the steps of a) transforming a supply current (Iin) having a base frequency, for example 50 Hz or 60 Hz, into an induction current (Iw) having a higher frequency than the base frequency of the supply current, b) feeding the induction current into at least one inductor of the induction heating cooking apparatus to generate a magnetic induction field, c) detecting a deviation or distortion of the actual shape or frequency spectrum of the supply current or a rectified supply current from a predetermined admissible shape or frequency spectrum lying outside of a pre-given tolerance range, d) adapting the induction current or the electrical power associated with the induction current until the detected deviation or distortion of the actual shape or frequency spectrum of the supply current or a rectified supply current from the predetermined shape or frequency spectrum lies within the pre-given tolerance range again.
