Abstract: The invention relates to a method for operating an induction hob (1), the induction hob (1) comprising a power circuit portion (2) with at least one switching element adapted to provide pulsed electric power to an induction coil (3) and a control entity (4) for controlling operating parameters of the switching element, the method comprising the steps of: performing a control loop with control cycles in order to detect coupling changes between the induction coil (3) and a piece of cookware, said control cycles comprising the steps of: receiving frequency information (fcurr) and power information (Pcurr) at said control entity (4); calculating at least one relation coefficient (Ds?, Ds?) based on said frequency information (fcurr) and said power information (Pcurr); and comparing said relation coefficient (Ds?, Ds?) with a relation coefficient boundary, thereby deriving a comparison result; deciding, based on the comparison result, whether to: perform a new control cycle of said control loop or whether t
