“…Wireless power transfer is the method that could deliver power without physical contact [1][2][3][4][5]. Several methods of wireless power transfer have been introduced including near-field wireless power transfer [6][7][8][9] such as inductive coupling through magnetic fields [10][11][12][13][14][15][16][17][18], capacitive coupling through electric fields [19][20][21][22][23][24][25][26][27][28], and far-field wireless power transfer such as laserbased optical power transmission [29][30][31][32][33] and RF microwave energy transmission [34][35][36][37][38][39][40]. Inductive wireless power transfer (IPT) utilizes a non-radiative magnetic field in the kHz to MHz range to realize the wireless power transfer function.…”

The IPT system has been studied for underwater applications such as autonomous underwater vehicles (AUVs) and subsea sensors. However, it rarely comparatively shows the performance of the IPT system in air, freshwater, and seawater. Based on the fore‐mentioned research background, this paper presents a survey of the properties of the IPT system in different mediums. Here, a 100 W power‐level experimental IPT prototype is built and tested. The resonant frequency is set at 300 kHz with a gap range from 10 to 190 mm. The comparison is focused on the efficiency, mutual inductance, coupling coefficient, coil resistance, and quality factor of the IPT system. The IPT system is placed in air, freshwater, and seawater with the same settings. What's more, the magnetic fields of coupling coils in air, freshwater, and seawater are presented in this paper. This paper could be acted as a reference to optimize the IPT system and facilitate future IPT research for underwater applications by analysing the performance of the IPT system in different mediums. The 3D Ansys Maxwell simulation of the IPT system is also given here to study the magnetic fields.

“…Authors in [14][15][16] consider the transfer of small powers while investigating the aspects of data transfer through the coupled pads. On the other hand, authors in [17] discuss an IPT system for low power levels focusing on the power electronics and its control algorithm, while considering two simple circular coils as transmitting and receiving pads. An interesting approach to the optimization of an underwater IPT system, also considering the eddy current losses in the medium surrounding the pads, is discussed in [18].…”

Design and Realization of an Inductive Power Transfer for Shuttles in Automated Warehouses

The inductive power transfer (IPT) is expected to greatly contribute towards electrification in transportation. In fact, IPT charging technology has the potential to overcome several limitations of conductive charging: in particular, the process can be fully automatable, and both static and dynamic charging are allowed, thus reducing the size of the battery pack. Additionally, safety is increased due to the absence of safety issues related to loss of cable insulation or to the unwanted interruption of the plug-socket connection. This paper presents, from a systematic approach, the design and realization of a prototype for IPT charging of autonomous shuttles in automated warehouses. First of all, the typical mission profile of the shuttle was properly identified, and a storage system based on power-oriented electrochemical cells was sized. Based on that, the architecture of the IPT system was chosen, both for transmitting and receiving sections. The pads were designed for this purpose, by considering the geometric constraints imposed by the manufacturer, through the utilization of the finite elements method. Finally, the power electronic circuitry was also designed. Numerical simulations of the components, as well as of the complete system, were performed and a prototype was built to widely verify the correspondence of the simulation outputs with the results obtained from an experimental measurements campaign.
