“…Multicoil IWPT systems have also been a dominant topic in the last few years. Most of the works focus on improving the power transfer or reducing misalignment by using more than one coil at the Rx side [213], the Tx side [219][220][221] or both sides [214,[222][223][224]. Regarding multiple receivers, Zeng et al [213] proposed a multi-directional magnetic coupler with a cuboid shape as the transmitter for a four arc-shaped receiver system for swarm AUVs (Figure 8e).…”

“…One such strategy involves spacing ferrite cores. One of the strategies involving spacing ferrite cores [213,229,230] is an option that does not require research into new materials. For instance, in [229], they modeled a 6.0 kW underwater IWPT system with several Rx core distributions that use less ferrite than usual cores, Figure 9c.…”

“…In [234], the authors presented a system able to transfer up to 130 W with a 73 mbps full-duplex communication. In [213], a partial Rx coil, a Tx coil and an additional transformer were used to transmit data and power, proving a data transfer rate of 30 kbps at a distance of 5 cm. Wang et al [235] designed a coaxially aligned underwater IWPT system that could transfer 518 W of power with an efficiency of 92% and 500 kbps/700 kbps full-duplex communication.…”

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.

Underwater wireless power transfer (UWPT) systems are appropriate for battery charging of compact, submerged devices without a complicated and expensive sealing structure or human contact because the power source and load are not physically connected. For the shore-based power supply situation, the underwater power conversion and junction technology should be required to drop down shore-based voltage to the target voltage for the underwater energy supply of the UWPT system. This paper proposes a lightweight, high efficiency and power density underwater power conversion connector system for the UWPT system, in which the LLC resonant converter is constructed with SiC transistors. The full load range zero-voltage switching (ZVS) and load adaptive characteristics have been achieved. The optimized RC level shift driver is adopted to highly reduce the switching loss of SiC transistors. Shore-based voltage of 1000 V was converted to the target voltage of 375 V for the UWPT system. The highest measured efficiency is over 98% at a load power level of 1500 W underwater conditions.

In this paper, an underwater single‐capacitor coupled wireless power transmission (USCC‐WPT) system is proposed, which operates at 200 kHz and can transmit 1 kW of power at 1 m in seawater with an efficiency of 76%. The USCC‐WPT system produces no eddy current losses in seawater, and the distance is increased compared to conventional inductive power transfer systems. The system proposed in this paper has a wide range of applications underwater. The load‐independent constant voltage (CV) output and misalignment tolerance properties of the USCC‐WPT system are analyzed and validated by an equivalent circuit model constructed from the stray capacitance. The 1 kW prototype demonstrates the feasibility of the USCC‐WPT system proposed in this paper, while the system can work properly with 50 cm misalignment.
