Estimating the term…
A sub-sea power delivery system includes a plurality of modular power converter building blocks on each of the power source side and the sub-sea load side that are stacked and interconnected to meet site expansion requirements and electrical load topologies. The power delivery system comprises a system DC transmission link/bus, wherein the system DC link is configured to carry HVDC or MVDC power from an onshore utility or topside power source to multiple sub-sea load modules. The stacked modular power converter topology on the sub-sea side of the sub-sea power delivery system is symmetrical with the stacked modular power converter topology on the on-shore/top-side of the sub-sea power delivery system.
A power delivery system comprising an AC power source configured to deliver power to one or plural AC loads via a DC transmission bus, the DC transmission bus comprising a sending end and a receiving end, the sending end coupled to a plurality of modular power converters configured in a stacked modular power converter topology, the receiving end coupled to a plurality of modular power converters configured in a stacked modular power converter topology, wherein the stacked modular power converter topology at the receiving end is symmetrical with the stacked modular power converter topology at the sending end, and wherein at least one receiving end modular power converter comprises a switching mechanism that is configured to operate as a modular power converter bypass switch, and further configured to regulate a DC link voltage for a corresponding modular stacked power converter.
