Hello Guys, I am at the HighSchool (Electrotechnic) and I have a nice evaluation project and want to build a Mini Induction Cooking Stove where the inductors should be arround 57cm diameter and powered from 24V DC. Now I have the problem to find the right formulas to calculate the Induction and the capacitor... Does someone have a circuit scheme and the formulas how to do this? Thanks Kayham

Thanks, yes I know, but how must I calculate the induction coil? There are some peoples working on this issue but currently have not found any usefull infos about the calculation of the inductor. From a parallal forum I have goten the info to use this product http://www.spulen.com/shop/product_info.php?products_id=1159 to build the induction coils I like to get arround 300 Watt output per inductor ... I have bought one on ebay but I do not know, how to change it for the use in 24V systems which is realy great idea exspecialy in Iran where we have very much solarpower. Thanks in Advance Kayham

It is not possible to convert a commercial induction stove to 24V. Try this: http://www.egsolar.de/english/home.htm

This solarcoocker is not what we need, because we have enought EnergyStorage for several weeks available du to a GelBattery manufacturer here in the city in northern Iran. For the 230V Induction Cooking Stove: I know, but I was about to figure out how it works... OK, NOW I know, I have the need for 2 primary coils of 69 rounds but I do not know the size of the copper (mm²) and then the inductor which is in between to two coils. Thanks Kayham

Maybe it would be easier to buy a inverter to use the battery voltage and convert it to 230V for a domestic induction cooker?

You and your circuit must be able to handle (al least) 13 Amps at 24V to get 300W. And: 300W isn't very much power for cooking... > but I do not know the size of the copper (mm²) As you must handle high currents: the more the better. > because we have enought EnergyStorage for several weeks available du > to a GelBattery manufacturer here in the city in northern Iran. So take 10 x 24V and you have 240VDC and a farily small current of 1.3 amp.

Right and I have gotten the idea from another thread, because if I use the normal induction cooking stove it has always 2000 watt and more, even if I have not much to cook. So, spliting the inductors into smaller parts could be the soulution which I wan to try out. Have a nice week Kayham
