- the power range can be from a low range, for example 50 watts to a few 100 watts, up to a few 100 watts or even at least one kilowatt is enough.
- a coil wire advantageously has with this number of turns, many individual strands. So suitable it is particularly good for this application due to the skin effect.
- a heating device can advantageously have a central control. This is connected to and controls all induction heating elements it evaluates or evaluates their operation, their signals such as with a cooking vessel detection as well as other data. It can the central controller can advantageously be designed such that it consists of a Feedback of a cooking vessel recognition, which by the individual Induction heating elements comes, an occupancy of the Heater recognizes. It can therefore determine whether, on the one hand, at all a cooking vessel suitable for induction heating is installed, or even several. Furthermore, it can be spatially distributed Signals from the individual induction heating elements recognize which one Place the cooking vessels and what induction heating elements do are sufficiently covered and should be operated. Furthermore it is possible to use one from an operator via the central control pass on the specified power to the individual induction heating elements to control them. In the case of a possibility mentioned above Bus systems can be controlled very easily via a central controller a certain induction heating element with the information about the desired performance level. About your own The induction heating element sets the power level information to the converter in the converter.
