Method for controlling an induction cooking hob with a plurality of induction coils and an induction cooking hob

Abstract

A method for controlling a cooking hob with one or more induction coils covered by a cookware and forming a cooking zone. All induction coils of the cooking zone are alternately activated. The method includes setting an average power to be transferred to the cookware by a user, determining a frequency, estimating a maximum average power if all induction coils of the cooking zone would be activated with said frequency, estimating a percentage power defined as quotient between the set average power and the estimated maximum average power, estimating a calculated number of coils defined as product of the number of coils within the cooking zone and the percentage power, defining a minimum number of simultaneously activated coils within the cooking zone by an integer value of the calculated number, and defining a temporal activation of a further one of the coils by a fractional part of the calculated number.
