“…For the design optimization of a high-frequency transformer, there are many objectives, such as minimizing the loss and volume. Regarding the design optimization parameters, dimensions (as shown in Figure 1d) and core materials (like nanocrystalline or amorphous) can be considered [29][30][31][32]. Detailed optimization models can be referred to these works as well.…”

“…In this paper, the topologies are henceforth referred to as axial and radial topology, corresponding to the direction of power transfer. Both transformer topologies have been discussed and applied in WPT systems in various research papers for a wide range of frequencies, power levels, and applications [4,[22][23][24][25][26][27].…”

This paper concerns the design of a high-frequency GaN-based rotating transformer confined by conductive materials. The design approach combines the high-order spectral element method for the magnetic modeling, an electronic circuit model, and the finite element method for the thermal modeling. The objective of the design analysis is to minimize the ratio of core inertia to efficiency. Two different transformer topologies are considered, in which the power is either transferred in the axial or radial direction. The resulting designs are compared in terms of efficiency, core inertia, and transferred power. The radial design shows the best performance within the optimization problem.

“…For a pot core rotating transformer, the different winding topologies in the rotating transformer were designed and optimized according to total core volume and power losses [17]. Furthermore, a multi-physical design method for high-frequency rotating transformers was proposed, where the PTE was optimized for different core geometries [18]. The design of the rotary transformer is mainly based on the combination of multiple physical fields, such as electric field, magnetic field, and thermal field, which increases the complexity of system design.…”

Cables or slip-rings are often used to power loads on a rotating unit in the rotation modulated inertial navigation system (RMINS). However, these power supply methods have the disadvantages of cable winding and slip ring friction and wear, which reduces the reliability and life of the RMINS. Therefore, this paper applies magnetic coupling resonant wireless power transfer (MCRWPT) technology to the RMINS to avoid the shortcomings of the above power supply methods. Furthermore, according to the structure and working characteristics of the RMINS, a simple design method of the MCRWPT system without any feedback control is proposed. Based on the ANSYS simulation, the magnetic shielding structure is designed to reduce magnetic leakage, and the efficiency of the MCRWPT system is optimized by designing the excitation frequency. Experiments verify the effectiveness of the proposed method. The experimental results show that the designed MCRWPT system can achieve an efficiency of 74.6% with an output power of 10 W and has been successfully applied to the uniaxial rotation module inertial navigation system. Finally, the design method of the MCRWPT system is simple, and it has guiding significance for the design of the wireless power transfer system in the RMINS.
