“…The result shows that the system is achieved the efficiency is 34.2% at k = 0.75 in the range from 100 kHz to 700 kHz. For each value R L = 70 Ω, C series = 13 -14 nF or C parallel = 6 -7 nF, there are corresponding the maximum power transfer efficiency [78]. They concluded that the selection of the coupling coefficient k at the suitable frequency, the value of the load resistance and the value of series or parallel capacitance is very important and essential to obtain maximum efficiency.…”

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.

“…In bio-medical implants, the partition between the coils and existence of tissues in between the sending and receiving coils are closely coupled. This avoids inserting power cable going through the skin [3]. However, the bio-implants coils in terms of size and separation are way different from those used for charging of electric vehicles.…”

This paper investigates the performance of circuit topology used in wireless power applications to optimize the level of maximum efficiency. We analyse the series and the parallel resonant topologies for use in an inductive coupling link to derive power transfer efficiency expressions verified using MATLAB. We look into the two topologies into the link under resonant conditions for selectively supplying the device with power. The results are obtained analytically which are verified subsequently by MATLAB simulation. We then analyse the links to see how maximum power transfer efficiency for a given pair of coils can be achieved. The topology at a given tuning frequency is used for powering a selected resistive load. The method is presented using a given pair of coils simulated and the results agree well with the theoretical explanation and derivations.
