Device for induction heating of cooking receptacles, of the type comprising at least two concentric induction coils supplied by a generator. Each induction coil (I1, I2, I3) is supplied by a separate generator (G1, G2, G3), the number of induction coils being equal to the number of supply generators. A control block (8) effects the independent operation of each supply generator (G1, G2, G3). The control block (8) is adapted to cause to operate according to a sequential order the supply generators (G1, G2, G3) during a detection step of the presence of a load on the corresponding induction coil (I1, I2, I3), starting with the generator (G1) corresponding to the innermost concentric induction coil (I1) and progressing to the outermost concentric induction coil covered by the receptacle (9) to be heated. The supply generators (G1, G2, G3) are identical to each other and have the same nominal power, for the modular replacement of one supply generator by another supply generator of the same characteristics.
