“…From efficiency in (21), it is noticeably clear that, coil to coil efficiency depends on resonance frequency, coupling coefficient and the load resistance. The derivation is done by considering all the vital parameters of the WPT circuit.…”

“…The LCL-Series topology from the Hybrid topologies is a variation of compensation architecture that allows an uninterrupted flow of current as well as output voltage in the transmitter, independent of the EV's misalignment [20]. Klaus et al [21] asserted that there appeared to be a considerable electromagnetic field leakage between the transmitter and the reception coil as a result of the wide air gaps. As a result of the threat this electromagnetic field leakage poses to people, it is crucial to reduce the magnetic leakage between the two coils.…”

<span lang="EN-US">The power efficiency of the wire free power transmission (WPT) system is tested in this article under various transmission distance circumstances, and the findings are utilized to investigate the best way to regulate the parameters for charging electric vehicles (EVs). The system`s power transfer efficiency is improved over using a fixed resonant frequency by altering it in response to changes in the coupling coefficient. In relation to resonance frequency, a trade-off between output power magnitude and power efficiency is also revealed. Through numerical simulation with Ansys, the trade-off resonant frequencies at various transmission lengths are determined by the analysis. Here, the transmitter and receiver employ circular coils with a circular cross-sectional area and a straightforward but effective series-series (SS) compensation architecture is used for comprehensive analysis.</span>

“…In addition, with a three-layer structure, the big number of coils results in high cost. There are also other attempts at optimizing shape and layout of multiple coils with regard to the gap between transmitting and receiving coils, etc., [12][13][14][15] but those are specific designs not suited for versatile use.…”

This paper proposes an optimal coil layout of wireless power transfer (WPT) systems for underwater vehicles (UVs). The power supply station adopts a multicoil arrangement with a double layer, and the UV also uses two receiving coils. The proposed WPT system for UVs has a reasonable advantage, where it does not request to adjust the relative position of coils. This paper experimentally discusses an optimal coil layout based on measurement results of a coupling coefficient. As a result, the proposed coil arrangement with the geometry rule realizes a certain power transfer under any positions and directions of UVs.
