Parallel Power for Undersea Application: The Basic Considerations

Power systems for undersea observatories are required to deliver high power with good reliability. For the proposed NEPTUNE observatory, the authors have developed a power scheme that combines ideas from terrestrial power systems and switching power supplies with experience from undersea cable systems. The system is based on a parallel network. This design can be applied to other undersea schemes, where it can allow longer cables with less copper. Key performance factors are explored in this paper
