Recently, unmanned aerial vehicles (UAVs) have shown immense potential in military and civilian applications. However, the limited endurance of UAVs poses a crucial challenge to their widespread adoption and development. Fortunately, wireless power transfer (WPT) technology has emerged as a promising solution to address this issue. In contrast to the previous papers on the topic, this review aims to provide a holistic top-down view of WPT technology for UAVs. More specifically, it introduces the fundamental principles of WPT technology firstly. Then, the design and optimization methods of coupling mechanisms, especially for UAVs, are introduced and compared. Numerous different and significant designs are reviewed and discussed. Furthermore, the compensation topology and control strategies are elaborated in detail subsequently. Finally, the key technical challenges faced by WPT for UAVs are put forward and future directions for development is proposed. Therefore, this review can be considered as an expedient reference for researchers conducting studies in the field of WPT technology for UAVs. Keeping this in mind, we present meaningful perspective for each of the analyzed key aspects, providing inspiration for what follows.

The paper focuses on three-dimensional (3D) spatial wireless power transfer (WPT) and the challenges of improving the isolation between coils in a multiple-coil system. We analyze the mutual inductance between coils to derive an isolation method and propose a 3D overlapping multiple-coil system with high isolation for spatial WPT systems. Through performance verification, the proposed coils are verified to achieve approximately -20.1 dB isolation and an average power transfer efficiency of approximately 61.5%, even in the presence of angular or lateral misalignments of the receiving coil. This represents an improvement of approximately 41.7% over conventional multiple-coil systems. Therefore, it can be considered a viable solution to address the limitations of degraded power transfer efficiency in WPT systems designed for spatial freedom.

This study proposes a novel approach for selecting the resonance capacitance of wireless power transfer systems, aiming to achieve a zero phase angle (ZPA) while simultaneously minimizing the leakage magnetic field. The performance of the method is validated across two key topologies: series–series (S–S or SS) and the double-sided inductor–capacitor–capacitor (LCC, LCC–LCC) topologies. By minimizing the vector phasor sum of the coil currents, the proposed approach effectively mitigates magnetic field leakage. The method is further validated through mathematical derivations, simulations, and experimental tests. The results reveal that using the proposed method to select resonance capacitances reduces the leakage magnetic field by up to 35.2% in the SS topology and by 42.0% in the double-sided LCC topology. Furthermore, the method improves the ZPA by more than 20° in both cases. These outcomes affirm the effectiveness of the proposed resonance tuning approach.
