Increased power transfer and heat generation in inductive heating applications through proper materials selection — •Marius Wodniok, Michael Feige, Werner Klose, Mikhail Tolstykh, Lennart Weber, and Sonja Schöning — Bielefeld Institute for Applied Materials Research (BIfAM), Bielefeld University of Applied Sciences, Department of Engineering Sciences and Mathematics, Interaktion 1, 33619 Bielefeld, Germany

Inductive heating is a well-established application of wireless power transfer. However, in this particular case there is a substantial need for optimization. Increasing the converted power while maintaining a high energy efficiency in combination with a homogeneous heat distribution are the leading requirements in that field.

We have performed finite element simulations using COMSOL Multiphysics in order to find the optimal material parameters of the transmitter coil environment and the receiving ferromagnetic metal film as well. An experimental induction heating setup is used to validate the simulated predictions. We have investigated a series of different ferrite materials, electrical steels and coil embedding environments.

According to our findings, it is possible to tailor the coil environment as well as the receiver's materials properties in a way that the energy transfer leads to in substantially increased heating performance.
