“…In a high-frequency alternating magnetic field, the current flows more concentratedly through the conductor's surface, while the current power in the middle of the material gradually decreases [57]. With the increase in frequency, the generation of eddy currents The results shown in Figure 6 indicate that during induction heating, as the heating frequency increases, eddy currents are generated at shallower positions from the surface, leading to a shift in the peak magnetic induction intensity towards the outer corner surface [56]. In a high-frequency alternating magnetic field, the current flows more concentratedly through the conductor's surface, while the current power in the middle of the material gradually decreases [57].…”

This paper describes the use of cold and hot composite forming technology to produce pointed curtain wall profiles. An electromagnetic–temperature coupling model was constructed using ANSYS to study the temperature and electromagnetic field distribution during the forming process. Numerical simulation was used to optimize the process parameters to obtain the optimum heating parameters with a current of 4000 A, a frequency of 35 kHz, and a duration of 2 s. The accuracy of the model was also verified through experiments. The simulation results show that the use of a conductive magnet can improve the induction heating efficiency, increasing the heating frequency and the temperature peak; however, it also increases the temperature difference. Sharp-corner curtain wall profiles were successfully produced using the optimized process parameters. The temperature of the heating zone was measured using an infrared thermal imager, and the relative errors between the maximum heating temperature obtained from the simulation and the actual measured values were 5.37% and 5.02%, respectively, indicating that the finite element model performs well in terms of prediction.

“…Induction heating is one of the most effective methods of energy conversion from the electrical to thermal form [2,3], used in diverse industrial processes such as preheating furnaces, heat treatments, welding, brazing, melting, etc [4,5]. It is thought to be more effective than other heating methods, such as resistance heating, because heat is generated directly within the workpiece during the induction heating process, as opposed to resistance heating, which first heats the heating element before transferring heat to the workpiece through conduction, which takes longer and ultimately results in more heat loss.…”

This paper describes the analysis and performance of a full-bridge LLC resonant converter based on power supplies for IH applications. The analysis contains five components: half bridge inverter, resonant tank, high frequency transformer, rectifier and coil. The switching bridge generates a square waveform to excite the LLC resonant tank, which will produce a resonant sinusoidal current which is transferred to the secondary of the converter through a high-frequency transformer. As it scales the voltage up or down according to the output requirements. The load represented by the equivalent circuit of the coil and work-piece is fed by the current transformed by the rectifiers. Considering that load parameters and resonant frequency vary greatly in all phases of system operation, this paper provides improved knowledge of output power control for high temperature applications. The validity of the analyzed converter parameters had been simulated and tested using MATLAB-SIMULINK software. The results of testing demonstrated that the proposed scheme and assembly has good efficiency, and it is well suited for magnetic induction heating systems
