Description

technical field [0001] The invention belongs to the field of wireless power transmission, and relates to a coil-coupled underwater wireless power transmitter. Background technique [0002] The total area of ​​the ocean is 3.6×108 square kilometers, accounting for 70.8% of the total area of ​​the earth. In this vast and rich ocean space, there are rich marine biological resources, ocean energy, ocean thermal energy and marine mineral resources. With the progress of industrialization and urbanization, the resources available on land are becoming less and less, and people are gradually paying attention to the effective use of marine resources. It can be said that the 21st century is the century when human beings march into the ocean. As an important means of exploring the ocean, even the only means in some cases, underwater vehicles are getting more and more attention. [0003] The main power supply mode of underwater vehicles is lithium-ion rechargeable battery, which has the...

AI Technical Summary

Problems solved by technology

In the research of wireless power transmission system, when the distance between the two coils at the transmitting end and the receiving end increases, the coupling coefficient between the two coils will definitely decrease, resulting in a decrease in power transmission efficiency and more power loss.

Therefore, there is a contradiction between increasing the transmission distance and improving the transmission efficiency in wireless charging.

[0008] (2) Unstable power transmission

These will affect the coupling of the coil, thereby affecting the efficiency of power transmission

[0009] (3) Low degree of automation

Different from the land wireless charging system, due to the influence of the water flow, the relative position and distance between the transmitting coil and the receiving coil are changing in real time, and even relative rotation will occur. Therefore, the land wireless charging system is not suitable for underwater wireless charging.
