I would like to know where can i find information about induction cooking, specifically about how variates the load versus the frequency of conmutation and the temperature
halgos:
Information on induction cooking can been found in applications sections of SCR, Triac and more recently in IGBT manuals. The system relies on a metalic cooking vessel, where eddy current inducted by an induction coil at some frequency (KHZ) cause heating. The vessel can be thought of as the shorted secondary of a transformer. When place near the induction coil, the vessel heats. When the vessel is moved away from the coil, the heating stops. The heating effect is similar to a gas stove. This system is used in many commercial stoves, and is quite effective. You cannot use glass pots on this type of stove.
