Induction device

An induction cooking appliance, comprising an induction device, said induction device comprising a plurality of induction areas, and a controller configured to control the plurality of induction areas within a control period from a first control interval and a second control interval repetitively with an alternating current frequency and to supply the plurality of induction areas with energy, wherein the induction areas are configured as individual inductors or as a plurality of inductors configured to be jointly controlled by a controller, said controller operating in the first control interval at least two of the plurality of induction areas with a first phase shift to minimize interference, wherein a phase angle of the first phase shift is calculated from a quotient from 180° and a number of the plurality of induction areas to be operated simultaneously within the first control interval.

A method for operating an induction device, comprising:

• controlling a plurality of induction areas independently of one another within a control period from a first and second consecutive control intervals repetitively with an alternating current frequency and to supply the plurality of induction areas with energy, wherein the induction areas are configured as individual inductors or as a plurality of inductors configured to be jointly controlled by a controller;
• and
• operating at least two of the plurality of induction areas with a first phase shift to minimize interference influence in at least one of the first and second consecutive control intervals, wherein a phase angle of the first phase shift is calculated from a quotient from 180° and a number of the plurality of induction areas to be operated simultaneously within the first control interval.
