Abstract: An induction based point heating system for cooking utensils or the like contains induction coils positioned below a plate, e.g. a glass ceramic plate. It is constructed as a cohesive component and includes induction generating means and the associated power, frequency generation or control electronics for the induction coils. The component is in the form of a flat plate or tray, which can be pressed from below against the plate. The induction coil is constructed as a flat, disk-like coil, which on its side remote from the plate is adjacent to a magnetic yoke such as a preferably segmented ferrite layer.
