  • Patent number: 11825585
    Abstract: The present invention relates to a method for controlling a cooking zone (16) of an induction cooking hob, wherein said cooking zone (16) comprises at least one induction coil (16) and is supplied by a generator (14) including a power switch. The method is performed by controlling the power switch by a gate driving signal (18) including a deactivation pulse length (Toff) and an activation pulse length (Ton). A switching period (T) of the gate driving signal (18) is given by the sum of the activation pulse length (Ton) and deactivation pulse length (Toff). A driving frequency (f) of the power switch is the reciprocal value of said switching period (T). The deactivation pulse length (Toff) depends on the resistance (28) and the inductance (30) of the induction coil (16). The activation pulse length (Ton) is varied according to a requested power for the cooking zone (16). A series of constant activation pulse length (Ton) is activated in order to determine the optimal deactivation pulse length (Toff).

  • Patent number: 11277888
    Abstract: A cooking hob includes at least one heating power transferring element with multiple concentrically arranged windings, one or more heating power energy units for powering the windings, a control unit that controls the heating power energy units, and detection means that determines the coverage of the windings by a cookware item. The control unit balances the heat provided to the cookware item by determining a rescaled electric power for the windings based on power requests and information regarding the coverage of the windings and establishes an operating cycle by determining a duty cycle for one or more windings. The duty cycle defines the activation time of the respective winding and is chosen such that the mean electric power provided to the respective winding within the operating cycle is equal or essentially equal to the rescaled electric power associated with the winding.
