Multi-layer and multi-material induction cookware has become a standard among manufactures due to its superior cooking performance and efficiency. Resonant converters are usually adopted to achieve an optimal power transfer at high supply frequency so that the load impedance modeling becomes of great importance. In this work a coupled finite element-circuit model of induction-efficient cookware is proposed. Equivalent circuit parameters are extracted from the FEM model in order to assess the resonance condition in a typical operating frequency range. The dependence on materials and layer distribution of the equivalent load is investigated by a parametric analysis.

Abstract
Multi-layer and multi-material induction cookware has become a standard among manufactures due to its superior cooking performance and efficiency. Resonant converters are usually adopted to achieve an optimal power transfer at high supply frequency so that the load impedance modeling becomes of great importance. In this work a coupled finite element-circuit model of induction-efficient cookware is proposed. Equivalent circuit parameters are extracted from the FEM model in order to assess the resonance condition in a typical operating frequency range. The dependence on materials and layer distribution of the equivalent load is investigated by a parametric analysis.Pubblicazioni consigliate
