A-High Efficiency Underwater Hybrid Wireless Power Transfer System with Low Plate Voltage Stresses
Published in IEEE Transactions on Power Electronics, 2024
This paper proposes a high-efficiency underwater hybrid wireless power transfer (UHWPT) system with low plate voltage stresses to ensure a safe and stable power supply for underwater electrical equipment. The power transfer channel is constituted by an integrated magnetic-electric coupler, formed by nesting coils into C-shaped plates and integrating them into the LC-compensated topology. The impact of the geometric dimensions and insulation on electrical parameters is explored to provide a reference basis for designing the integrated magnetic-electric coupler. A system design method based on the double optimization parameters is hereby proposed. Then, an experimental prototype is set up to verify the feasibility of the design method. Experimental results show that the system achieves the load-independent constant current (CC) output with a maximum efficiency of 87.8%.
