A method for heating a container (Ri) placed on a cooktop including heating elements which are associated respectively with inductors which form elements for detecting the presence of the container and are distributed along a frame which is embodied such that it is two-dimensional in a cooking area. The method includes searching (E) a heating area (Zi) having the heating elements arrangement which are at least partially covered by the container and computing (E) a power supplied by each heating element of the heating area (Zi) according to a total specified power (Pi) associated thereto and the degree of coverage of each detection element associated to heating element by the container (Ri). Utilization, in particular, is for an inductive cooktop.

Method for heating a container (Ri) placed on a cooktop including heating elements which are associated respectively with inductors which form elements for detecting the presence of the container and are distributed along a frame which is embodied such that it is two-dimensional in a cooking area. The method includes searching (E) a heating area (Zi) consisting of the heating elements arrangement which are at least partially covered by the container and computing (E) a power supplied by each heating element of the heating area (Zi) according to a total specified power (Pi) associated thereto and the degree of coverage of each detection element associated to heating element by the container (Ri). The invention can be used, in particular for an inductive cooktop.

A supply generator for an oscillating circuit, includes an inductance (L) and a resonant capacitor (C, C), for operation at a fixed frequency and also includes at least one pair of transistors (I, I), operated on a variable cyclic regime for modifying the power. The generator includes a first diode (D) between a first transistor (I) and the supply for the generator and a second diode (D) between the junction point of the inductance (L) and the resonant capacitor (C, C) and the junction point of the first transistor (I) and the first diode (D). The invention is of particular use for supply of the cooking rings on an induction cooking hob.
