“…They designed an impedance matching network that could achieve a 100 W power transfer. In another paper by Guo et al [196], they designed a coaxial IWPT system with a position adaptive power delivery system to reduce the effect of misalignment with an efficiency of 88% for a 300 W power transfer. In [197], they designed another coaxially aligned IWPT device with high misalignment tolerance and that was compatible with a funnel-type docking station.…”

Unmanned underwater vehicles (UUVs) are key technologies to conduct preventive inspection and maintenance tasks in offshore renewable energy plants. Making such vehicles autonomous would lead to benefits such as improved availability, cost reduction and carbon emission minimization. However, some technological aspects, including the powering of these devices, remain with a long way to go. In this context, underwater wireless power transfer (UWPT) solutions have potential to overcome UUV powering drawbacks. Considering the relevance of this topic for offshore renewable plants, this work aims to provide a comprehensive summary of the state of the art regarding UPWT technologies. A technology intelligence study is conducted by means of a bibliographical survey. Regarding underwater wireless power transfer, the main methods are reviewed, and it is concluded that inductive wireless power transfer (IWPT) technologies have the most potential. These inductive systems are described, and their challenges in underwater environments are presented. A review of the underwater IWPT experiments and applications is conducted, and innovative solutions are listed. Achieving efficient and reliable UWPT technologies is not trivial, but significant progress is identified. Generally, the latest solutions exhibit efficiencies between 88% and 93% in laboratory settings, with power ratings reaching up to 1–3 kW. Based on the assessment, a power transfer within the range of 1 kW appears to be feasible and may be sufficient to operate small UUVs. However, work-class UUVs require at least a tenfold power increase. Thus, although UPWT has advanced significantly, further research is required to industrially establish these technologies.

Based on the principle of magnetic coupling resonance, a wireless power transmission system with electromagnetic coupling mechanism based on E-type magnetic core is designed for autonomous underwater vehicle (AUV). Firstly, according to the special circular structure of AUV and the effect of seawater mobility, an electromagnetic coupling structure that can be used in AUV is proposed. The performance of the electromagnetic coupling mechanism is tested by simulation and experiment. The coupling coefficient of the coupling mechanism can reach 0.64, and it has good magnetic field confinement ability. Secondly, in order to improve the robustness of the system, the compensation network of the LCL/S topology is used. Finally, an experimental platform is built. When the incandescent lamp is used as the load, the output power is 120W, and the efficiency can reach 96%. When the load changes, the output voltage can remain constant. When the relative positions of the transmitting and receiving coils are changed at the same time, axial misalignment and rotational misalignment experiments are carried out. In the experiment, the output voltage is relatively stable, which indicates that the system has high misalignment tolerance ability.

“…In microwave bandpass filters [19][20][21][22], waveguide resonators are used to achieve narrow bandwidth with better insertion losses and high power handling capabilities [22]. Similarly, in wireless power transfer (WPT), the waveguide technique (relay resonators or repeaters) is used to transfer power over longer distances and achieve maximum transfer efficiency [23][24][25][26]. This paper, however, focuses the study of MI waveguide technique to communicate over longer distance without adding additional computational processing or power consumption to the network.…”

Magneto-inductive (MI) waveguide technology is often proposed to increase the MI communication distance without adding significant cost and power consumption to the wireless sensor network. The idea is to add intermediate relaying nodes between transmitter (Tx) and receiver (Rx) to relay the information from Tx to Rx. Our study of MI wave-guides has realized that adding a relay node improves the communication distance, however, the performance is greatly dependent on the position of the relaying node in the network. We therefore, in this work have investigated the effect of placement of a relay node and have determined the optimal relay position. We have performed various sets of experiments to thoroughly understand the behavior and identified three main regions: (a) for region 1, when the distance between Tx and Rx is equal or less than the diameter of the coils ( d ≤ 2 r ), the optimal relay position is close to Tx, (b) for region 2, when the distance between Tx and Rx is greater than diameter of the coils but less than twice the diameter ( 2 r < d < 4 r ), the optimal relay position lies in the center of Tx and Rx, and (c) for region 3, when the distance between the Tx and Rx is equal or greater than twice the diameter of the coils ( d ≥ 4 r ), the optimal relay position is close to Rx.
