A cook top with at least two heating elements includes a power electronics arrangement connected to a domestic single phase AC supply. The power electronics arrangement includes several power supply units, which each supply heating currents to one or more heating elements, and a switch arrangement with several electromechanical relays for connecting/disconnecting the power supply units to/from the heating elements. Output poles of at least two electromechanical relays associated with different power supply units are connected in parallel, wherein the parallel connection is permanently connected to at least one of the heating elements. This arrangement reduces the number of switching processes required for alternating use of a power supply device with several heating elements, and simplifies compliance with electromagnetic compatibility standards.

Cook top comprising at least two heating elements and a power electronics arrangement

A cooktop apparatus, in particular an induction cooktop apparatus, includes a switching unit configured to interrupt and establish current flow from a current supply, a first switching element receiving the current flow during an operating process, a control apparatus, which controls the switching unit during the operating process such that the switching unit interrupts the current supply during a first time interval which has a duration of less than of half a period of the power supply voltage. The control apparatus causes the current supply to be connected during the operating process immediately before and immediately after the first time interval. The first switching element begins switching and ends switching during the first time interval.

Hob device

An induction hob having a plurality of induction heating elements; a control unit to operate the plurality of induction heating elements so as to heat at least one flexibly definable heating zone in a synchronized manner; and a measurement array to measure a heating power generated by the plurality of induction heating elements. The measurement array measures a sum of heating powers of at least two induction heating elements and the control unit uses the sum of heating powers to regulate the heating power generated by the plurality of induction heating elements.

Induction HOB comprising a plurality of induction heaters

A frequency converter circuit has at least two outputs that are respectively connected to a load, in particular an induction coil. A first output is operated at a first switching frequency and a second output is simultaneously operated at a second switching frequency that is different from the first, in such a way that noise having a frequency generated by the superposition of the first switching frequency and the second switching frequency is produced. The frequency converter circuit is operated in such a way that the frequency of the noise is lower than a first cutoff frequency and/or is higher than a second cutoff frequency.An induction cooking device includes first and second induction heating elements, and a frequency converter circuit including first and second power outputs electrically coupled to the first and second induction heating elements, respectively. The frequency converter circuit generates first and second power output signals with first and second switching frequencies applied to the first and second power outputs, respectively. The second switching frequency is selected to be no greater than a first cut-off frequency and no less than a second cut-off frequency (e.g., higher than the first cut-off frequency). The induction cooking device regulates electrical power applied to the first and/or second outputs by adjusting the switching frequency and/or a duration during which at least one of the first and second switching frequencies are applied in a repeating cycle during which the electrical power applied to the first and/or second outputs.
