“…In the literature, different WPT technologies have been investigated, for example, IWPT and resonant IWPT (Li and Mi, 2015;Hata et al, 2018;Patil et al, 2018;Machura and Li, 2019), CWPT (Mostafa et al, 2017), and OWPT (Fakidis et al, 2016;Yoshida et al, 2016;Jin et al, 2018;Katsuta and Miyamoto, 2018;Jin and Zhou, 2019), and have been employed in various realistic systems.…”

Toward Thing-to-Thing Optical Wireless Power Transfer: Metal Halide Perovskite Transceiver as an Enabler

et al. 2021

This paper proposes a novel conceptual system of optical wireless power transfer (OWPT) between objects, which is different from the existing OWPT systems such that a single device—an optical transceiver—is employed. This optical transceiver, which is capable of both absorbing and emitting light, is fabricated from a metal halide perovskite known for its superior features that can help significantly reduce the whole system size and cost. The proposed system contributes to realizing a thing-to-thing OWPT network, in which surfaces of objects/things are covered by perovskite transceivers (fully or partially), enabling them to wirelessly charge or discharge from the others.

“…They include: wireless charging of the batteries for electrical vehicles [1][2][3]; wireless charging of mobile robots; wireless charging of the batteries for biomedical implanted devices [4]; dynamic electrical vehicle charging [5]; WPT to moving sensors [6]; WPT to wireless sensor networks nodes [7,8]. WPT also may have some more useful but unusual applications: WPT of solar energy from space to the Earth [9]; wireless charging of the batteries for drones while hovering [10]; wireless charging of the batteries for unmanned autonomous submarines [11,12]; wireless powering of unmanned autonomous aircrafts [13,14].…”

Suppression of Radiated Emissions from Inductive-Resonant Wireless Power Transfer Systems by Using Spread-Spectrum Technique

et al. 2022

Inductive-resonant wireless power transfer systems are often used for wireless transfer of electric power. However, they are significant sources of radiated electromagnetic emissions. The effect of spread-spectrum approach based on classical switching frequency modulation of inductive-resonant wireless power transfer system inverter operating frequency and multi-frequency technique on the radiated emissions and efficiency is studied experimentally in detail. The influence of the classical frequency modulation and multi-frequency technique parameters on the peak radiated emission levels and the efficiency of the inductive-resonant wireless power transfer system are investigated more comprehensively. It is shown in the paper that the spread-spectrum approaches can lead to an appreciable radiated emissions reduction with small or large impact on the system’s efficiency. Some useful recommendations on how to choose parameters of the periodic switching frequency modulation or the multi-frequency technique considering a trade-off between the radiated emissions reduction and the efficiency are also proposed.

“…The biggest difference between the IPT system in the marine environment and the air is reflected in two aspects: One is that seawater has conductivity, which is a typical multiphysics coupling problem [2]. The other is that the impact of ocean currents affects the stable transmission of electrical energy in the IPT system [3][4][5][6][7][8][9].…”

Wireless charging in the marine environment has problems such as high loss and low efficiency. In order to solve these problems, based on the wireless power transmission technology in the seawater environment, this paper studies the multi-physical field coupling relationship of the underwater IPT system. Through researching on the law of mutual influence and interaction between the fields, the relationship between the physical fields is established. The software is used to establish a system simulation model, the dataset is solved and analyzed to get the distribution of electric field, magnetic field, thermal field, and flow field, which provides a theoretical basis for the model and optimization of the IPT system in the seawater.
