Abstract (en)
[origin: WO2006117182A1] The aim of the invention is to operate induction coils (L1, L2) of an induction cooking hob (11) with as little noise as possible. Said aim is achieved by operating the induction coils (L1, L2) at the same frequency f<SUB>g</SUB> (mode of operation a) or at a frequency difference ?f of about 18 kHz (mode of operation c), especially during alternating operation. Changing back and forth between said modes of operation makes it possible to reach predefined values (P<SUB>1</SUB>, P<SUB>2</SUB>) for the power of the induction coils (L1, L2) at the mean-time value while disturbing noise is prevented from developing.
