Marine power distribution arrangement

A marine power distribution arrangement utilizes generators (14) driven at standard or higher than normal speeds and/or having a number of poles to produce electric power at a standard 50/60Hz frequency or substantially higher than the standard 50/60Hz frequency, such as 400Hz. Each generator (14) is a multi-phase, multi-circuit generator supplying isolated outputs on a plurality of lines to a propulsion power converter (22,26) having isolated inputs to provide variable frequency, variable voltage power to a ship propulsion motor and to a service power converter to provide ship service power at a standard AC frequency or DC and at standard voltage for a service load. With this arrangement, power conversion transformers can, for the most part, be eliminated, thereby reducing the size and weight of the distributions system.
