Patent ID: 10939506

Abstract:
The invention relates to a method for controlling an induction hob (1), the induction hob (1) comprising a plurality of induction coils (3) and two or more power units (4), each power unit (4) being coupled with one or more induction coils (3), wherein a cooking zone is formed by associating one or more induction coils (3) to a coil group (6.1-6.4), the method comprising the steps of: —defining one or more coil groups (6.1-6.4), each coil group (6.1-6.4) being associated with one or more induction coils (3); —calculating a relative power value or relative electrical parameter value of each coil group (6.1-6.4) based on a maximum power value or maximum electrical parameter value, the maximum power value being the power value of the coil group with the highest power request, respectively, the maximum electrical parameter value being an electrical parameter value of the coil group (6.1-6.4) with the highest power request; —calculating, for each coil group (6.1-6.4), a coil activation number based on the relative power value or relative electrical parameter value, the coil activation number being the number of induction coils (3) to be activated in subsequent steps of a coils activation sequence; —establishing a coils activation schedule based on the coil activation number; —operating the induction hob (1) according to the coils activation schedule. wherein the power units (4) are operated according to a master-slave configuration, wherein a master power unit is adapted to calculate the coil activation number, establish the coils activation schedule and operate the plurality of induction coils (3) of a master power unit and one or more slave power units according to the coils activation schedule.
