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.
Claims9
A power feed for a submarine communications system, comprising a plurality of power converters connected together in series to convert a low voltage received at an input to the power feed to a high voltage at an output of the power feed, in which each power converter has at least two step-up transformer stages and wherein at least one of the secondaries of the windings of the or each transformer in at least one of the first transformer stages of at least one of the plurality of power converters is a primary of a second of the transformer stages and is wound using a high voltage insulating wire.
