“…The constant of the above equivalent circuit is the value by reflecting the measured inductance, resistance, and 2D finite element simulation iron loss data. As shown in Figure 11, this paper adopts a series-series system in which the resonance capacitor and the coil are connected in series because a regeneration can be easily performed from the symmetry of the circuit in this system [7].…”

“…Although ferrite cores have a weaker structural strength, they have a lower core loss than silicon cores. The resonant circuit between inductance and capacitor in the primary circuit is applied to supply the secondary voltage in the WPT [7]. The measured inductance value is applied to circuit simulation to increase the accuracy of the analysis.…”

This paper proposed the transformer characteristic analysis method for the wireless power transfer (WPT) device and linear motor (LM) integration system that can be applied to industrial cleanroom transfer systems. A cable is required to supply the power in conventional systems. In comparison, the proposed system utilizes a WPT device that can simplify power transfers and make a better space utilization. The shape of the wireless power transmission system is proposed along with the discussion of the 2D FEA analysis method about the inductance analyzing method, which are important parameters in magnetic coupling. In addition, ferrite iron loss was calculated based on the analysis results, and applied to the entire modeling circuit to verify the validity of the measured and analyzed values. Finally, the proposed analysis method for the transformer coupling characteristics of the wireless power transfer combined with the transfer system is verified by experiments and simulations.
