2 - THE OPERATING PRINCIPLE
2.1. - Analogy with the transformer
An induction hob operates due to the electromagnetic properties of most containers used on traditional
hobs.
one can compare this hob with a transformer of which the secondary winding would have been
shorted. A significant internal current arises therein and causes quick heating.

The saucepan can be compared with a shorted set of concentric whose internal resistance is not zero.
From the function keys, you control the electrical power supply to the transformer primary winding
which generates a magnetic field. This field induces currents at the bottom of the container placed on
the hob. These induced currents heat the container immediately, which transmits the produced heat to
the food inside. Cooking is performed efficiently with almost no loss of energy. The appliance heating
power is pushed to its maximum.
