ABSTRACT:
In a single wire underwater power distribution system, parallel branching nodes are added in a manner that makes the branch connection and branch line look like a series node to the shore based power source. The primary side of a DC—DC converter functioning as an ideal transformer working down to DC is connected into the series line where a branching series line is desired. One side of the secondary creates the branched series path. The other side of the secondary goes to seawater ground, establishing a new local seawater ground.
