Abstract (en)

[origin: WO2021115871A1] The invention relates to an induction device (10a; 10b; 10c), in particular an induction cooking device, comprising a plurality of independently controllable induction areas (12a, 14a, 16a, 18a; 12b, 14b, 16b, 18b; 12c, 14c, 16c, 18c) and comprising at least one control unit (20a; 20b) which is provided to repetitively control the induction areas (12a, 14a, 16a, 18a; 12b, 14b, 16b, 18b; 12c, 14c, 16c, 18c) within a control period (22a; 22b) formed by a first control interval (26a; 26b) and at least one second control interval (28a; 28b) with at least one AC frequency (24a; 24b) and to supply same with energy. In order to provide a generic device with improved characteristics in terms of safe and/or comfortable operation, in the first control interval (26a; 26b), the control unit (20a; 20b) operates at least two of the induction areas (12a, 14a, 16a, 18a; 12b, 14b, 16b, 18b; 12c, 14c, 16c, 18c) with a first phase shift (32a; 32b) in order to minimise interferences.
