Abstract
An inductive cooker heating system has a high frequency-supplied induction coil. The thickness or wire thickness of the single conductors for a conventional frequency between 20 and 30 kHz (25 kHz), is approximately 0.2 mm. This limited wire thickness has proved to be particularly low-loss. The arrangement of the induction cooking point comprises a thermal insulation placed below a plate for receiving cooking vessels, a shield with branched, grounded line structures and a disk-like induction coil, which is back-connected on the underside by a ferrite yoke plate.
