Submersible contactless power delivery system
First Claim
1. A submersible contactless power transfer system for transferring power from a power source to an electric load, comprising:
- a first conductor coupled to one of the power source or the electric load;
a core-mounted submersible conductor coupled to the other of the power source or the electric load; and
a submersible magnetic core supporting and surrounding a portion of the core-mounted conductor, with the core-mounted conductor and magnetic core surrounding a portion of the first conductor and submersed in a liquid for transferring power from the source to the load.

Abstract
A submersible contactless power transfer system, especially for powering underwater electric loads, including movable loads, such as underwater vehicles, elevators, or worksite equipment. A converter supplies high frequency power to a conductor loop. A coupling sheath or link has a core-mounted conductor at least partially surrounded by a magnetic core which slidably receives a portion of the conductor loop within the link. An optional secondary converter converts power from the core-mounted conductor to meet the load requirements. A contactless power distribution system is submersible to deliver power to underwater loads through clamped-on or captive links attached at any location along the conductor loop. Methods are also provided of powering loads submersed in water, including seawater, or other non-magnetic liquid mediums.

10. A submersible coupling link, comprising:
-
a submersible sheath conductor for surrounding a portion of an elongate power conductor, the sheath conductor for coupling to an electric load submersed in a liquid; and a submersible magnetic core surrounding the sheath conductor to provide a flux path for a magnetic flux induced therein when the sheath conductor and core surround the power conductor, said magnetic flux inducing a current flow within the sheath conductor to deliver power from the power conductor to a load when coupled therewith. - View Dependent Claims (11, 12, 13, 14, 15)
