Abstract
A medium-voltage (MV) power conversion system receives a MV AC power source, and converts the MV AC power source into DC power sources to supply power to loads. The MV power conversion system includes a plurality of power modules, and each power module includes a MV AC switch and a MV isolated AC-to-DC converter. The MV isolated AC-to-DC converter is connected in series to the MV AC switch. Input sides of the plurality of MV AC switches are connected to each other, and connected of the MV AC power source so that the plurality of MV isolated AC-to-DC converters individually convert the MV AC power source into the DC power sources.

A medium-voltage power conversion system, configured to receive a medium-voltage AC power source, and convert the medium-voltage AC power source into at least one low-voltage DC power source to supply power to at least one load, the medium-voltage power conversion system comprising:
- a plurality of power modules, and each power module comprising:
- a medium-voltage isolated AC-to-DC converter,
- wherein input sides of the plurality of power modules are connected to each other, and respectively connected to three phase inputs of the medium-voltage AC power source so that the plurality of medium-voltage isolated AC-to-DC converters individually convert the three phase inputs of the medium-voltage AC power source into the at least one low-voltage DC power source.
A distributed medium-voltage power conversion system, comprising a plurality of medium-voltage power conversion systems, wherein each medium-voltage power conversion system comprises a plurality of power modules, and each power module comprises:
- a medium-voltage isolated AC-to-DC converter,
- wherein input sides of the plurality of power modules are connected to each other, and respectively connected to three phase inputs of the medium-voltage AC power source so that the plurality of medium-voltage isolated AC-to-DC converters individually convert the three phase inputs of the medium-voltage AC power source into the at least one low-voltage DC power source,
- wherein the plurality of medium-voltage power conversion systems, configured to respectively receive a medium-voltage AC power source, and convert the medium-voltage AC power source into at least two low-voltage DC power sources to supply power to at least two loads.
