Abstract

A contactless power transfer system, especially for powering electric loads, hazardous loads or underwater loads and the like. 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 delivers power to a variety of loads through clamped-on or captive links attached at any location along the conductor loop. Methods are also provided of powering a movable electric load, or a stationary load from a movable source, and of distributing power to a plurality of portable electric loads.
