Abstract

The invention relates to a circuit device (1) for a cooking device, in particular cooking hob, more in particular induction cooking hob, comprising- at least two, in particular two, three or at least three power units (P1, P2, .. PN), each power unit supplied with electrical power by a different mains current phase (L1, L2, .. LN),- wherein each power unit (P1, P2, .. PN) comprises frequency converting means (G11 .. GNM), each for supplying at least one induction element with electrical power to generate heating power,- wherein each power unit (P1, P2, .. PN) comprises at least one current conversion unit (C1 .. CN) for converting an in-put direct or alternating current into one, at least one, two or at least two output direct currents,- wherein each power unit (P1, P2, .. PN) comprises at least one load or at least two loads, in particular one or more low-power loads and/or control units, supplied or to be sup-plied with electrical power by the output direct current, an output direct current or the output direct currents from the current conversion unit,- wherein a first power unit (P1) comprises a first current conversion unit (C1), in particular for converting an alternating current from a first mains current phase (L1) into one, at least one, two or at least two first output direct currents (I1),- wherein by the first output direct current or one of the first output direct currents (I1) of the first power unit (P1), at least a second current conversion unit (C2) of a second power unit (P2) is supplied for converting the first output direct current (I1) into one, at least one, two or at least two second output direct currents.
