“…The authors combined the RIC-WPT system with a class-E inverter as a transmission to improve the overall efficiency of the system because zero voltage switching and zero derivative switchings (ZVS/ZDS) are conditions to reduce the switching loss softswitching technique and to obtain high power-delivery efficiency. With 1 MHz of resonant frequency and 50 Ω of load resistance, the efficiency of two coils proposed system reached to 49.4% [97]. In [98], by adding more class-DE rectifier as a receiver and designing the specification for self-inductance, resistances, the system achieved a better result at 73% overall efficiency or 9.87 W (50 Ω) output power, coils distance of 10 cm.…”

Wireless power transfer (WPT) techniques are being popular currently with the development of midrange wireless powering and charging technology to gradually substitute the need for wired devices during charging. Unmanned Aerial Vehicles (UAVs) are also being used with many practical purposes for agriculture, surveillance, and healthcare, etc. There is a trade-off between the weight of the UAVs or their batteries and their flying time. In order to support those UAVs perform better in their tasks, WPT is applied in UAVs to recharge batteries which help to increase their working time. This paper highlights up-to-date studies that are specific to near-field WPT deploying into UAVs. The charging distances, the transfer efficiency, and transfer power, etc. are considered to provide an overview of all common problems in using and charging UAVs, especially for autonomous landing and charging. By classification and suggestions in specific problems will be provided opportunities and challenges with respect to apply near-field WPT techniques for charging the battery of UAVs and other applications in the real world.
