  • Power feed for a submarine communications system
    Patent number: 6275396
    Abstract: A power feed for a submarine communications system includes a plurality of power converters each of which has at least 2 step-up transformer stages in which at least one of the windings of at least one of the transformer stages of at least one of the plurality of power converters is wound using a high voltage insulating wire to insulate against a high DC voltage appearing at an output of an adjacent power converter. The use of high voltage insulating wire removes the need for expensive custom built DC blocking capacitors.
