“…However, it is challenging to design induction coils for complex-shaped mechanical parts. The simultaneous dual frequency (SDF) heating method uses two different frequencies of currents to harden the surface layer of a gear with a uniform contour thickness [5] and this has focused on achieving more even temperature distribution along the outer contour of gears [6,7]. In SDF, medium frequency current and high frequency current are used simultaneously.…”

This paper presents the development of a simultaneous dual frequency (SDF) induction hardening apparatus for gear hardening process. First, 2D FE modeling for thermal-electromagnetic coupled field is introduced for gear hardening and the analytical results are investigated. By modeling the gear hardening as 2D FE model, we can calculate for the coupled field more efficiently. And optimum process parameters can also be found through this analysis. A real SDF heat treatment equipment is manufactured using analytical results like input frequency and gear hardening experiments are conducted. Through analysis and experiments, we can validate the performance of the developed machine.

“…The coils are equally spaced to obtain the maximum possible transmission efficiency [11], so, the DC are equal to that the domino MCR-WPT system and the DS MCR-WPT system. There are both CC and DC in the domino MCR-WPT system.…”

“…Recent efforts to increase the size of the coil and operating frequency of the system have been successful in extending the transfer distance [10]. Once the system operating frequency reaches over-mega-hertz, however, the winding loss grows excessive [11], and the coil takes up an unwanted amount of space. Further, when the system works in the sub-mega-hertz for mid-range WPT, coils fabricated from metamaterial are very expensive [12].…”

The use of multi-resonators for medium-range wireless power transfer (WPT) systems is an important concern; the cross-couplings between non-adjacent coils have an adversely impact on the transmission distance and efficiency of the system. This paper proposes a dumbbell-shaped (DS) coil in a WPT system. The DS coil structure was analyzed theoretically and verified experimentally. The proposed scheme eliminates cross-couplings between non-adjacent coils in the multiple resonator system to resolve frequency drift, and improve the transmission distance and efficiency in the multiple resonator system. The scheme features a coplanar structure which can secure direct-coupling and save space when applied in the home, office, and public areas.

“…The coil and vessel are similar to the primary and secondary of a transformer. Based on this, induction cooking load in referrence to the coil is modeled as a series R eq -L r circuit for constant switching frequency operation [12], [20]- [24]. R eq is the referred equivalent resistance and L r is the referred equivalent inductance to the coil, respectively.…”

Inverter configurations for multiple-load induction cooking applications need development. Inverter configurations for induction cooking applications are used in home appliances based on single coil inverters. For multiple-load configurations, multiple coils are used. They require proper inverters, which provide independent control for each load and have fewer components. This paper presents a three-leg inverter configuration for three load induction cooking applications. Each induction coil powers one induction cooking load. This configuration operates with constant switching frequency and powers individual loads. The output power of the required load is controlled with a phase-shift control technique. This configuration is simulated and experimentally tested with three induction loads. The simulation and experimental results are in good agreement. This configuration can be extended to more loads.
