With the development of wireless power transfer (WPT) technology, it is possible to transfer power to the batteries without plug-in cables and human interaction for autonomous underwater vehicles (AUVs), taking advantage of high safety, high reliability and unattended capability. However, when implementing the WPT system under the seawater environment, the electrical properties of seawater including the permittivity and the conductivity cause a significant changing in the parasitics of winding coils underwater. The seawater, which owns higher permittivity and conductivity compared to the air, not only causes extra parasitic capacitance to coils but also conducts extra eddy current loss, and thus reduces the system efficiency. In this paper, the characteristics of winding coils underwater are investigated and an optimized design methodology for underwater WPT system with series-series (SS) compensation is proposed. A 200-W underwater WPT prototype is built and experimentally verifies the analysis for the coils and the optimized design approach. The experimental demonstration also shows the system efficiency comparison between the air, the water, and the seawater environments.

“…From the voltage gain range, some novel derivatives are deduced to attain certain improvements [16][17][18][19]. The literature [16] presents a resonant converter with a lossless impedance control network (ICN). The unique ICN structure could maintain good soft-switching features across wide operating ranges.…”

In this paper, a structure-reconfigurable resonant DC-DC (direct current -direct current) converter is presented. By controlling the state of the auxiliary switch, the converter could change the resonant structure to acquire a high efficiency and wide voltage gain range simultaneously. The characteristics of the LLC (inductor-inductor-capacitor) resonant converter are firstly analyzed. Based on this, through introducing additional resonant elements and adopting the topology morphing method, the proposed converter can be formed. Moreover, a novel parameter selection method is discussed to satisfy both working states. Then, a detailed loss analysis calculation is conducted to determine the optimal switching point. In addition, an extra resonant zero point is generated by the topology itself, and the inherent over-current protection is guaranteed. Finally, a 500 W prototype is built to demonstrate the theoretical rationality. The output voltage is constant at 400 V even if the input voltage varies from 160 to 400 V. A peak efficiency of 97.2% is achieved.Energies 2019, 12, 2905 2 of 25 efficiency is another requirement to be met. To sum up, DC-DC converters with a high efficiency and wide voltage gain range have considerable research significance.Energies 2019, 12, x FOR PEER REVIEW 2 of 25 high conversion efficiency is another requirement to be met. To sum up, DC-DC converters with a high efficiency and wide voltage gain range have considerable research significance.
