Several magnetic couplers have been presented for IPT-based charging of Unmanned Aerial Vehicles (UAV) with different sizes, transmission distances, power ratings, and landing gears. Therefore, it is hard to conclude the superiority or suitability of existing couplers for a given UAV application without evaluating their performance under common indices. Thus, a comparative analysis of existing IPT couplers for UAVs is conducted in this paper, considering electromagnetic and physical performance indices. This includes efficiency, leakage magnetic field, misalignment tolerance, receiver coil volumetric power density, weight, and total harmonic distortion (THD) of transmitter and receiver currents. The validity of the analysis is experimentally supported. This paper identifies the following: relative advantages and disadvantages of existing couplers, the best couplers suited for different landing gears of UAVs in the rotary-wing category, the impact of compensation on UAV coupler performance, and the best overall performing couplers. Moreover, future directions are suggested based on the drawbacks identified through analysis.(Note that the organization of the body of the paper is at the authors' discretion; the only required sections are Introduction, Methods and Procedures, Results, Conclusion, and References.

“…To make the coupled coils resonate at the desired frequency, which is the frequency of the HF power supply ω s , capacitors can be used in four topologies: (i) series-series (SS), (ii) series-parallel (SP), (iii) PS, and (iv) PP [21]. Here, the SS topology is used, in which the natural resonant frequencies of the coupled coils are fixed versus the variations in coil-coil distance, due to lack of magnetic cores.…”

Wireless charging is widely considered as a safe and reliable way for powering biomedical implants, as it avoids problems like surgical infection. Wireless power transfer (WPT) systems are desired to work efficiently against variations in coil–coil distance or output load. On the other hand, to maintain the maximum overall efficiency of the WPT system, the high frequency (HF) power amplifier, used to feed WPT system, must operate at optimal zero‐voltage switching (ZVS) condition. In this paper, an automated dual‐objective control strategy adaptive to variations in coil–coil distance or output load is proposed which ensures both targets of tracking maximum power point and operating at optimal ZVS condition by adjusting operating frequency and duty‐cycle of switching voltage of HF power amplifier, respectively; that is while there have been few studies which have addressed both the two targets. To evaluate the effectiveness of the proposed strategy, a PCB prototype, operating at 800 kHz, is fabricated. Experimental results, demonstrating the proposed strategy increases transferred power from 23 mW to about 45 mW, are in good agreement with theoretical predictions. Additionally, while implanting the receiver coil in a real biological tissue, experiments show only 2% of degradation in power transfer efficiency as well as no frequency shift.
