PRINCIPLES OF INDUCTION
Operational Principles
An induction cooktop operates thanks to the electromagnetic properties of most containers used on the traditional
cooktop.
At a first approximation, you can compare this cooktop 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 can control the electrical power supply to the transformer primary
winding that generates a magnetic field. This field induces currents at the bottom of the contain-
er placed on the cooking zone. These induced currents heat immediately the container, which
transmits the produced heat to the food contained inside. Cooking is performed practically with-
out any loss of energy. The appliance heating power is pushed to its maximum.
