Micro-T Circuit Model for Double and Single Sided Induction Heating Systems摘要
A method is given for obtaining a phase terminal equivalent circuit, which is useful for the analysis of traveling wave as well as longitudinal flux induction systems for heating thin metal strips. The excitation is transverse to the direction of strip motion and can be realized as a three phase system or a single phase system where the strip could be ferromagnetic or nonmagnetic. First, a general form of the field solution is obtained using transfer matrices. A variable transformation is then made which makes it possible to derive an equivalent circuit for each planar region in the system. By joining the equivalent circuits in cascade, an equivalent circuit for the complete system is obtained. The voltages and currents in the equivalent circuit relate directly to the field quantities within the actual system.
