“…Considering the listed limitations and the initial stage of capacitive WPT research for underwater power transfer, so the application of wireless power transfer in underwater environments will focus on more matured Inductive WPT technologies. This technology was first used in air medium, wireless charging pile position of electric vehicles in transportation field [23,24], pocket wireless charger of the miniature electronic pacemaker in the medical field [25,26], and wireless transmission of industrial field and smart homes [27,28]; however it has gradually been extended to seawater medium owing to advancement and high demand for this technology [29,30]. Due to the particular complexity of seawater environment, wireless power transfer is faced with serious electromagnetic wave attenuation [31,32], irregular disturbance of seawater ocean current, difficult docking of charging equipment and other problems [33,34], and its efficient transmission has not been fundamentally solved [35][36][37][38][39].…”

Comprehensive research on the wireless power transfer technology of autonomous underwater vehicles is necessary to address the issue of significant energy loss in such vehicles during wireless power transfer. Previous analysis on factors that affect wireless power transfer in seawater environment demonstrated that the eddy current loss generated during transmission and offset of the coupling mechanism are the main factors that degrade the efficiency. In this study, existing literature on wireless power transfer for autonomous underwater vehicles in recent years is reviewed, and it is concluded that the energy loss during underwater wireless power transfer can be effectively reduced through coupling mechanism optimization, adaptive control, and docking device design. This study analyses the challenges of low-loss wireless power transfer for autonomous underwater vehicles and the prospects for future development trends and research areas, providing a reference for realizing efficient and flexible energy supply for autonomous underwater vehicles.

This paper presents a detailed analysis of the safety of human bodies in the electromagnetic field generated by inductive power transfer (IPT) systems designed for kitchen appliances. Comparisons of basic and reference limit values of various safety standards are investigated through theoretical circuit analysis and extensive simulation studies. Simulation models of human bodies along with an IPT system for kitchen appliances are established to reveal the effect of the electromagnetic field on the human body. Corresponding experiments are conducted via constructing a configuration of the designed IPT system and simulating the standing position. Both experimental and analytical results indicate that it is easier to fulfill international safety standards by increasing the operating frequency of the IPT system for kitchen appliances, and hence, the safety of human bodies can be effectively improved.

“…Common dielectric materials mica, polypropylene, polyimide, and fiberglass sheets are adopted to compare the proposed structure. The low frequency (less than 100 kHz) medium power (more than 300 W) capacitor-free multi-layer coil can be potentially applied on some curved surfaces of the appliances due to the coil flexibility and thickness [20,21].…”

With the rapid development of wireless power transfer (WPT), the self-resonant WPT system without using additional compensation capacitors has attracted attention. However, most of reported self-resonant WPT systems have low power transfer (less than 100 W) and high operating frequencies at megahertz. In this paper, four multi-layer, self-resonant WPT coil pads with different dielectrics are designed and experimentally validated. The aim of this paper is to increase the power rating and decrease the operating frequency for capacitor-free WPT system compared to reported systems used in consumer electronics. Analysis of integrated compensation capacitance, inductance, and parasitic capacitance of the coil is provided. Finite Element Analysis (FEA) is used to evaluate four dielectric materials, mica, polypropylene, polyimide, and fiberglass. An experimental setup has been developed, which can achieve more than 360 W power transfer for a 120 mm air gap with an efficiency of 82% and an operating frequency of near 80 kHz.
