(orcid)0000-0002-5996-0474 Induction heating of two magnetically independent loads with a single transmitter 2022 Access copy available to the general public Unrestricted This article introduces 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 heats 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 system's geometry, coil's number of turns, and compensation capacitors. A finite-element model is used to simulate the magnetic fields generated by inductor currents and calculate the impedance matrix. With the impedance, capacitor values and inductors’ number of turns are selected with the objective of achieving a high power ratio between the top and bottom zones, as well as minimizing stress in the electronics. First, a prototype was built to validate the impedance results in the small-signal regime, and then, the full power regime was used to verify power and current simulations info:eu-repo/grantAgreement/ES/MICINN/PID2019-103939RB-I00 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 6.7 2022 ENGINEERING, ELECTRICAL & ELECTRONIC 42 / 274 = 0.153 2022 Q1 T1 3.341 2022 Electrical and Electronic Engineering 2022 Q1 14.1 2022 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Lope, I.
