Abstract

The invention relates to an induction hob comprising a circuitry (1a) for powering at least one induction coil (6), the circuitry (1a) comprising a power circuit portion (7) with at least one switching element (4, 5) adapted to provide pulsed electric power to said induction coil (6) and an oscillating circuit portion (9) comprising at least one resonance capacitor (9.1, 9.2) which is associated with a resonance capacitor voltage, said induction coil (6) being electrically coupled with said power circuit portion (7) and said oscillating circuit portion (9), wherein said induction hob comprises a control entity (10), said control entity (10) being configured to provide and/or receive resonance capacitor information, specifically, sampled resonance capacitor voltage values, applying a discrete mathematical transformation to the resonance capacitor information thereby obtaining modified resonance capacitor information, said control entity (10) being further configured to calculate first and second electrical information related to the induction coil (6), specifically information regarding the amplitude of the electric current (Ic) provided through said induction coil (6) and information regarding the phase delay between the electric current (Ic) provided through said induction coil (6) and the voltage applied to the induction coil (6) based on said modified resonance capacitor information.
