Abstract:
1. A direct current (DC) power transmission system comprising: a first plurality of series connected power collection systems, wherein each of the first plurality of series connected power collection systems includes a power source; a plurality of alternating current (AC) to direct current (DC) power converters coupled to respective series connected power collection systems of the first plurality of series connect power collection systems, wherein each of the AC to DC power converters comprises at least one half bridge section; and at least one superconducting DC conductor configured to transmit power generated by said plurality of power collection systems to a remote load, the superconducting DC conductor further comprising a first set of conductors radially surrounded by a second set of conductors, wherein conductors of the first set of conductors are electrically isolated from each other, wherein at least one conductor of the first set of conductors is electrically coupled to the first plurality of series connected power collection systems via at least one of the AC to DC converters such that the at least one half bridge section of the at least one of the AC to DC converters maintains constant current at the at least one superconducting DC conductor based on current supplied by each of the first plurality of series connected power collection systems.
