Submersible power distribution system and methods of assembly thereof
First Claim
1. A submersible power distribution system comprising:
- at least one receptacle exposed to an underwater environment;
a plurality of power conversion modules positioned within said at least one receptacle, wherein each of said plurality of power conversion modules comprises;
a first enclosure exposed to the underwater environment, said first enclosure defining a first interior cavity having a first pressure;
at least one second enclosure positioned within said first interior cavity, said at least one second enclosure defining a second interior cavity having a second pressure that is lower than the first pressure, said at least one second enclosure restricting exposure of non-pressure-tolerant power electronics in said second interior cavity to the first pressure; and
a wet-mateable connector coupled to said first enclosure and extending between said first interior cavity and the underwater environment.

Abstract
A submersible power distribution system is provided. The system includes at least one receptacle configured to be exposed to an underwater environment and a plurality of power conversion modules positioned within the at least one receptacle. Each of the plurality of power conversion modules includes a first enclosure configured to be exposed to the underwater environment, the first enclosure defining a first interior cavity configured to have a first pressure. Power conversion modules also include at least one second enclosure positioned within the first interior cavity. The at least one second enclosure defines a second interior cavity configured to have a second pressure that is lower than the first pressure. The at least one second enclosure is configured to restrict exposure of non-pressure-tolerant power electronics in the second interior cavity to the first pressure.

14. A method of assembling a power conversion module, said method comprising:
-
providing a first enclosure exposed to an underwater environment, the first enclosure defining a first interior cavity having a first pressure; providing at least one second enclosure defining a second interior cavity having a second pressure that is lower than the first pressure; identifying non-pressure-tolerant power electronics of the power conversion module; positioning the non-pressure-tolerant power electronics within the second interior cavity, wherein the at least one second enclosure restricts exposure of the non-pressure-tolerant power electronics in the second interior cavity to the first pressure of the first interior cavity; positioning the at least one second enclosure within the first interior cavity; and coupling a wet-mateable connector to said first enclosure and extending between said first interior cavity and the underwater environment. - View Dependent Claims (15, 16, 17, 18, 19)
