In this paper, the optimization of a small planar circular spiral coil on a magnetic substrate for a higher quality factor (Q-factor) is presented. By proposing a volume filament model, inductance and ohmic resistance, including the skin and proximity effects of the coil on the magnetic substrate, are calculated. For verification, a printed planar spiral coil with 9 mm radius, 0.15 mm thickness, and...
Both AC transport current and magnetic field which are generated by the AC transport current lead to energy loss so called transport AC loss in power equipments using superconducting tapes. The transport AC loss is closely related to stability and efficiency of superconducting power equipments. Therefore, we need to deal with the transport AC loss characteristics of the superconducting tapes under...
