There is a wide literature concerning the application of inductive power transfer (IPT) to light railway systems. In this work, proposed application is innovative with respect to existing literature: static current collection on conventional railway lines is proposed in order to replace the functionalities implemented by conventional battery chargers and the so-called railway “parking” system. According to standards in force, current collection in standstill conditions is limited since pantograph contact shoes and catenary wires have to be protected by thermal overload. These limitations have to be considered since power demand for all the services installed on modern coaches should be higher than 20-40kW. This is a critical technical issue especially for long compositions that have to be prepared for service by activating on-board subsystems such as heating and air conditioning. Additional possible applications should be related to refrigerated wagons in freight compositions. In all these cases the availability of a simple, safe, and compact system should be useful to ensure a wireless power collection to on-board equipment. In this work authors introduce the proposed application and perform some preliminary design considerations. With respect to current literature on IPT systems, authors also introduce some innovative design criteria based on the analogy between resonant electrical system and corresponding mechanical ones. In this way, sizing of the proposed IPT system can be performed using modal methods that are also used for the proper sizing of mechanical vibrating systems, such as example, vehicle suspensions, or pantograph systems.

“…Wireless power transfer (WPT) systems have proven their reliability and have become a widely used technique. A WPT system transfers power for many applications, such as implantable medical devices (IMDs) [1][2][3], the charging of electric vehicles (EVs) [4][5][6][7][8][9], autonomous underwater vehicles (AUVs) [10], unmanned aerial vehicles (UAV) [11], robotic systems [12], light detection and ranging equipment [13], and the Internet of Things (IoT) [14][15][16]. In addition, it is used in some appliances, for instance, smartwatch straps [17], smartphones [18], battery-powering systems [19], and electrical drones [20,21].…”

A cylindrical joint structure for wireless power transfer (WPT) systems is proposed. The transmitter (Tx) and receiver (Rx) coils were wound on hemicylindrical and cylindrical structures, respectively. The Rx coil rotates freely around the axial direction of the Tx coil. Different methods of winding the Tx and Rx coils are given and discussed. Electromagnetic fields (EMFs) around the WPT windings should be lower than the limits set by WPT standards. Therefore, the WPT windings were designed to reduce EMF level and maintain constant power-transfer efficiency (PTE). The design procedures of the windings are discussed in detail. EMF analysis was done under different rotation angles (α). The selected design reduced the variation of the mutual inductance (M). As a result, it maintained a constant PTE while rotating the Rx coil between 0° and 85°. Moreover, leakage magnetic fields (LMFs) near the WPT coils of the chosen design were reduced by 63.6% compared with other winding methods that have the same efficiency. Finally, a prototype was built to validate the proposed idea. Experiment results were in good agreement with the simulation results. The WPT system maintained constant efficiency in spite of the rotation of Rx coil, where efficiency dropped by only 2.15% when the Rx coil rotated between 0° and 85°.

“…Since an epoch-making technology based on the magnetic resonant coupling wireless power transfer (MRCWPT) incredibly realized the energy migration by a cordless way in 2007 [1], the seemingly magic MRCWPT systems have been widely applied in various fields, such as portable electronic devices, medical equipment, electric vehicles, integrated circuits, and so forth [2,3,4,5,6]. For its remarkable virtues of movability, flexibility, and convenience, the MRCWPT technology is also an ideal technical solution to develop the smart home engineering in the near future [7,8,9,10]. The MRCWPT technique has attracted more and more attention from the researchers of the charging field [11,12,13,14,15].…”

Dramatic advancements have been witnessed for the magnetic resonant coupling wireless power transfer technology used in various portable electronic devices. A novel omnidirectional wireless power transfer system was proposed in this paper. Instead of conventional planar coils, a multidirectional receiver inside the transmitter was designed to receive the electromagnetic energy from all the directions. As expected, the finite element simulation results show that the distribution of magnetic field is uniform at different positions inside the transmitter. And the power transfer efficiency (PTE) of the newly designed system with the multidirectional receiver is obviously greater than that of the conventional system with the planar coil. Effects of the different receiver structural sizes on the system performance were discussed. PTE of the system becomes higher when the receiver is larger. Furthermore, PTE is insensitive to position and angular misalignment of the multidirectional receiver. The experimental measurments show that PTE of the system with the multidirectional receiver is 26% at the frequency of 6.78 MHz. The newly designed magnetic resonant coupling wireless power transfer system will be significative for the electronic devices indoor.
