Abstract: 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.

Abstract: 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.
