Abstract:
An induction heating arrangement (1000) including four coils of a smaller diameter (1100, . . . , 1400) and a coil having a larger diameter (1500) is provided. The coils are arranged on a first plane (2100) and on a second plane (2200). In order to adapt a cooking area (1600) to the size of a pot, either the larger coil (1500) or one or more of the smaller coils (1100, 1400) are operated. A power supply circuitry (2400) is shared between the coils of the two planes. A selector (2300) disconnects a respective coil of the plane of coils that is not operated in order to avoid coupling, interference and loss of energy. Guiding elements of the magnetic flux (1110, 1115, 1540) confine the magnetic field in the area of the pot. A method of operating the induction heating arrangement is also provided.
