摘要： An induction generator is connected to a three-phase mains. The induction generator includes a control unit (10) connected to a current transformer (38), on one (L1) of the lines (L1, L2, L3) of the three-phase mains. The induction generator includes a number of power sections (26, 28, 30, 32, 34, 36). Each power section (26, 28, 30, 32, 34, 36) supplies one of the induction coils (40, 42, 44, 46, 48, 50). A control unit (10) estimates and corrects harmonic distortions of the mains current via the current transformer (38). The power transferred to a heated object as a function of the frequency is stored in a memory of the control unit (10), so that the heated object is identifiable by its frequency-power characteristic. The frequency spectrum of the transferred power related to a harmonic distortion in the line (L1) is stored in the memory (10) if the distortion exceeds a predetermined limit. The harmonic distortions are corrected by the control unit (10) if a heated object with the frequency-power characteristic related to the harmonic distortion is detected.

摘要： The present invention relates to an induction cooking hob (10) including a number of heating zones (12, 14, 16, 18). Each heating zone (12, 14, 16, 18) comprises or corresponds with at least one induction coil. Each induction coil is connected to a generator. Two or more heating zones (12, 14, 16, 18) are linked or can be linked into a cooking area by a user. The linked heating zones (12, 14, 16, 18) are controlled by a common power setting. An operator interface is provided for operating the heating zones (12, 14, 16, 18). A control unit is provided for controlling the heating zones (12, 14, 16, 18). The operator interface includes actuating elements corresponding with predetermined links (20) between the heating zones (12, 14, 16, 18). The control unit is provided for synchronizing the generators of the linked heating zones (12, 14, 16, 18) by one common controller.

摘要： The present invention relates to an induction generator for induction heating elements, in particular for induction coils of a cooking hob. The induction generator is connected or connectable to different lines (L1, L2, L3) of a three-phase mains. The induction generator includes a control unit (10) connected to a current transformer (38), placed on one (L1) of the lines (L1, L2, L3) of the three-phase mains. The induction generator includes a number of power sections (26, 28, 30, 32, 34, 36). Each power section (26, 28, 30, 32, 34, 36) is provided for supplying one of the induction heating elements (40, 42, 44, 46, 48, 50). The control unit (10) is provided for estimating and correcting harmonic distortions of the mains current via the current transformer (38). The power transferred to a heated object as a function of the frequency is stored or storable in a memory of the control unit (10), so that the heated object is identifiable by its frequency-power characteristic. The frequency spectrum of the transferred power related to a harmonic distortion in the line (L1) supplying the control unit is stored or storable in the memory of the control unit (10), if said harmonic distortion exceeds a predetermined limit. The harmonic distortions of the mains current are corrected or correctable by the control unit (10), if a heated object with the frequency-power characteristic related to the harmonic distortion is detected.
