ABSTRACT:
An arrangement for controlling induction coils of an induction cooking hob so as to minimize noise production resulting from intermodulation of certain frequencies of operation. The induction coils are operated in two modes, with a first mode at the same frequency fgso to produce a low intermodulation or differential frequency, or at a second mode having a high differential frequency of about 18 kHz. Alternating back and forth between said modes of operation makes it possible to reach predefined average values for the power of the induction coils for a given time period, while at the same time minimizing development of disturbing noise.
