“…Rectangular coils are more prone to eddy current losses due to increased inductance at corners and create hotspots. However, rectangular coils have shown a better lateral displacement than circular coils, improved effective flux distribution area [138], [139]. Polarized pads consist of two or more coils that generate flux perpendicular and parallel to the plain on resting, aiding to increase in transmission distance, CoC, shielding effect, misalignment tolerance and power transfer capability.…”

Unmanned Aerial Vehicles (UAVs) are becoming increasingly popular for applications such as inspections, delivery, agriculture, surveillance, and many more. It is estimated that, by 2040, UAVs/drones will become a mainstream delivery channel to satisfy the growing demand for parcel delivery. Though the UAVs are gaining interest in civil applications, the future of UAV charging is facing a set of vital concerns and open research challenges. Considering the case of parcel delivery, handling countless drones and their charging will become complex and laborious. The need for non-contact based multi-device charging techniques will be crucial in saving time and human resources. To efficiently address this issue, Wireless Power Transmission (WPT) for UAVs is a promising technology for multi-drone charging and autonomous handling of multiple devices. In the literature of the past five years, limited surveys were conducted for wireless UAV charging. Moreover, vital problems such as coil weight constraints, comparison between existing charging techniques, shielding methods and many other key issues are not addressed. This motivates the author in conducting this review for addressing the crucial aspects of wireless UAV charging. Furthermore, this review provides a comprehensive comparative study on wireless charging's technical aspects conducted by prominent research laboratories, universities, and industries. The paper also discusses UAVs' history, UAVs structure, categories of UAVs, mathematical formulation of coil and WPT standards for safer operation.

“…their uniform magnetic field [14], can provide a large inductive coupling in comparison with spiral coils [6], [9], [14]- [17]. Examples of such systems include high-voltage battery charging [11], [18], [19] and WPT through-metal-walls [20]- [22]. It should be noted that selecting the coil topology is mainly influenced by the application's spatial restriction.…”

“…② With x-, y-, or z-misalignment, only two main couplings (MP1S1 and MP2S2) work, and the cross-couplings (MP1S2, MP1P2, MP2S1, and MS1S2) should be small enough to be neglected. Quadruple D pad (QDP) is reported in [31] and [32] for laptop and EV charging applications. In this paper, a quadrature pad (QP) is added to the QDP to form the QDQP, as shown in Fig.…”

Pad misalignments are almost inevitable in most inductive power transfer (IPT) systems. It tends to cause parameter variations and thus significantly affecting the performance of the IPT system. In this paper, a hybrid IPT system with misalignment tolerance using quadruple D quadrature pads (QDQPs) is proposed to tolerate x-, y-, z-and diagonal misalignments with load-independent output voltage, simplifying or even canceling control schemes. Besides, the proposed approach can restrict the increase of the primary current when the secondary side moves out of the operating region. Moreover, a new parametric design method is presented according to the misalignment characteristics of QDQPs. The method can limit the output voltage fluctuation to a certain range given a predetermined misalignment distance. A 3.5-kW prototype was built to verify the proposed hybrid IPT system. The primary and secondary coil sizes are both 400 mm×400 mm and the air gap is 150mm. Experimental results demonstrate that the proposed hybrid system can tolerate -150 mm to +150 mm x-misalignment, -150 mm to +150 mm y-misalignment, -20 mm to +35 mm z-misalignment, and -100mm to +100mm diagonal misalignment with load-independent output voltage. Within the predetermined misalignment range, the output voltage fluctuation is less than 5%.
