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.
