Electrical Dimensioning of Inverter-inductor-load System in Induction Heating of Ferromagnetic Plates as Load

Abstract

An important practical field of induction heating is the heating of ferromagnetic plates. A significant part of the heating arrangement is a medium-frequency - so called length-field - heating inductor. It is supplied by a medium-frequency inverter of serial resonance circuit. The paper presents the detailed dimensioning method of the inductor-load system, based on approximating analytical computations, together with the interaction between that and the inverter. It gives the computed results for a concrete situation.
