摘要
A novel double-layer (DL) combined windings transverse flux induction heating (TFIH) system is used to address the inhomogeneous eddy current density problem which dominates the thermal distribution on the surface of work strips. The single-phase winding of a typical TFIH system is replaced by a double-layer combined one, which enables the magnetic fluxes generated by each phase to interact and complement each other to compensate for the weak magnetic areas that otherwise would generate more uniform and concentrated eddy current density and temperature distribution. In order to attain the performance of the proposed DL-TFIH system, an interpolative finite element analysis modeling method is introduced in this paper. Simulation results of the proposed systems are compared with a typical TFIH device.
