The design of a system capable of heating two magnetically independent ferromagnetic loads placed on different horizontal planes, which uses a combination of induction heating and inductive coupling, called inductively coupled heating. The system uses a single primary inductor acting as a transmitter to transfer power to a secondary inductor attached to the bottom load, which is connected electrically with a third inductor that heads the top load. Since power of the whole system is supplied by a simple half bridge inverter, the ratio of the delivered power to each of the loads, which is critical for cooking results, is entirely dependent on the systems geometry, coil's number of turns, and compensation capacitors. The proposed system utilizes a unique coil design and control algorithm to efficiently transfer energy to both loads, while maintaining precise control over the heating process. The advantages of this approach includes reduced material costs, increased reliability, simplified design.
