“…These benefits have made WPT an attractive technology in industrial, commercial and consumer applications. WPT is used in electric vehicle (EV) charging [3], [4], charging robots [5], material handling systems [6], biomedical implants [7], underwater vehicle charging [8], [9] and many others. Among its many applications static and dynamic electric vehicle charging [10], [11] are most promising.…”

This paper introduces a single-phase bidirectional AC-AC Matrix type converter for wireless power transfer (WPT) applications. The proposed converter converts mains 50 Hz alternating current (AC) directly to high frequency 85 kHz AC without an intermediate direct current (DC) conversion stage. A minimum cost realization of only two bidirectional AC switches comprised each of two semiconductor device and one gate drive signal is employed. The converter operation modes are quantum energy injection and circulating self-oscillation. Elimination of the DC link introduces a sag in the power transfer during the zero crossing of input AC mains, which is well documented in literature. A novel H-bridge buffer structure is introduced which eliminates the power sag by storing energy during mains peak and delivering energy during the zero-crossing period. The converter operates with inherent zero current switching, thus achieving a low switching loss and electro-magnetic interference. The control feature ensures that the converter can be used for both static and dynamic wireless charging applications. The bidirectional power transfer capability ensures that the system can operate in both grid to vehicle (G2V) and vehicle to grid (V2G) power transfer modes. The proposed converter design is analyzed analytically and verified through thorough simulation study.

“…A method for designing high quality spiral resonators with transmission efficiency up to 95% is suggested in [14]. In [15], targeting the two main problems of seawater attenuation and resistance, a lightweight self-locking coupling structure on the receiving side is proposed to improve the coupling coefficient to resist ocean current interference. [16] proposes a coil structure composed of two transmitting coils and one receiving coil, and the eddy current loss is reduced by half while the transmission efficiency is improved by about 10%.…”

In this work, particular and general solutions to Airy’s inhomogeneous equation are obtained when the forcing function is one of Airy’s functions of the first and second kind, and the standard Nield-Kuznetsov function of the first kind. Particular solutions give rise to special integrals that involve products of Airy’s and Nield-Kuznetsov functions. Evaluation of the resulting integrals is facilitated by expressing their integrands in asymptotic series. Corresponding expressions for the Nield-Kuznetsov function of the second kind are obtained.

“…One of the most attractive advantages of the capacitive-based WPT is the avoidance of undesired eddy currents and electromagnetic interfaces (EMI) that come with magnetic-based WPT methods [20]. In the marine environment, the hull will have more impact on the power transfer and the electromagnetic fields or the electric fields for the conductive feature of seawater which is compared with the air medium [21][22][23][24][25][26]. In Fig.…”

Underwater wireless power transfer (UWPT) system has attracted widespread attention. It has been used for power delivery for underwater equipment in the marine environment with high safety and convenience. However, the material of metal plates and the shape which will affect the high frequency alternating electromagnetic fields and the high frequency alternating electric fields for the inductive wireless power transfer (IPT) system and the capacitive wireless power transfer (CPT) system. This paper presents the effects of the hull of the autonomous underwater vehicle (AUV) on the underwater wireless power transfer system including the underwater capacitive wireless power transfer (UCWPT) system and underwater inductive wireless power transfer (UIWPT) system. The features of underwater wireless power transfer systems have been carefully studied with simulation and experimental work. The experimental water tank has been constructed with the 35‰ salinity water. The hull of AUVs has been respectively simulated and built with rectangle metal plates and curved metal plates. The original experimental data and phenomenon have been presented in this paper. The different performance of the UCWPT system and UIWPT system is provided and discussed in this paper. The comparison work with the related paper has been analyzed. This paper could be acted as the reference for designing the underwater wireless power transfer system for AUVs.INDEX TERMS Underwater wireless power transfer (UWPT), capacitive, material, shape, autonomous underwater vehicles (AUVs)
