Abstract：In recent years, the second-generation high temperature superconducting (HTS) coated conductor, particularly Yttrium Barium Copper Oxide (YBCO), has been widely applied in fields including electric power, medicine, transportation, military, and energy. This is due to its high current-carrying capacity and superior mechanical and electromagnetic properties within the 20~77 K temperature range. A compact charging suspension system based on the HTS coil is designed, which can simultaneously realize wireless charging and self-stabilized suspension, and can be applied to wireless power supply suspension exhibition for small objects. This innovative system solves the issues of complex devices and limited continuous power supply time caused by the need todesign a specific magnetic circuit structure and install a built-in battery or power supply in the existing electromagnetic levitation and electrodynamic suspension technology. Through theoretical derivation and finite element analysis, it demonstrates that introducing the HTS coil with low resistance and high current density into the wireless power transfer (WPT) system can significantly enhance the output power and efficiency of the system, with a maximum increase of 3 times and 2.6 times, respectively. Specifically, the output power growth rate of the HTS-Cu WPT system increases from 54% to 199%, and the output efficiency growth rate increases from 88% to 162%, compared to studies done on the transmission performance of the Cu-Cu WPT system and the HTS-Cu WPT system at different suspension heights. Furthermore, the study compared the properties of copper and HTS coils, finding that the AC resistance of the HTS coil consistently remains lower than that of the copper coil under identical conditions. As the system frequency decreases, the disparity in the quality factor Q between the copper and HTS coils widens, suggesting that incorporating an HTS coil in the low-frequency range significantly enhances the transmission performance of the WPT system. Additionally, the frequency characteristics of the load voltage in both the HTS-Cu WPT system and the Cu-Cu WPT system were measured and aligned with finite element analysis results, thereby validating the accuracy of the simulation model. Finally, the experimental platform of the HTS-Cu wireless charging suspension system was constructed. The frequency characteristic of the load voltage in the HTS-Cu WPT suspension system was measured and compared with those of the Cu-Cu WPT system and another HTS-Cu WPT system. The results show that the load voltage for all three systems peaked at their respective resonance points of 60 kHz, 60 kHz, and 62 kHz, with maximum values of 4.14 V, 4.02 V, and 4.37 V, respectively. This demonstrates that including the HTS coil increased the maximum output voltage by 0.12 V and 0.35 V, respectively. However, it is essential to note that the spatial magnetic field generated by the permanent magnet structure in the HTS-Cu WPT suspension system increased the AC losses, thereby slightly reducing its transmission performance relative to the HTS-Cu WPT system, although it still outperformed the Cu-Cu WPT system. Meanwhile, the experiment illustrates that the system cannot move laterally or spin within a range of 10 mm, and maintain an efficient and constant load voltage output.
