Abstract (en)

[origin: EP2506665A2] The device has two heating frequency units, where an intermediate output power of one of the heating frequency units is adjusted under minimizing of a flickering parameter. The heating frequency unit is operated in a time interval with a set of frequencies (f1a, f2a) and in another time interval with another set of frequencies (f1b, f2b) that differs from the former set of frequencies, where the two sets of frequencies differ from each other around 14 kHz. A controlling unit is provided in an operating state to periodically operate the heating frequency units with time period. An independent claim is also included for a method for operating a cooking device.
