Claim:
1. A direct current to alternating current inverter sub-system for a high voltage direct current distribution system, said direct current to alternating current inverter sub-system comprising: an enclosure; a direct current to direct current galvanically isolated buck converter including a direct current input electrically connectable to a high voltage direct current cable and a direct current output, wherein the direct current to direct current galvanically isolated buck converter is structured to provide galvanic isolation between the direct current input and the high voltage direct current cable to avoid ground currents in the high voltage direct current cable; and a direct current to alternating current voltage source inverter including a direct current input electrically connected to the direct current output of said direct current to direct current galvanically isolated buck converter and an alternating current output electrically connectable to an alternating current transmission line, wherein said direct current to alternating current voltage source inverter is mounted in said enclosure with said direct current to direct current galvanically isolated buck converter, in order that the direct current output of said direct current to direct current galvanically isolated buck converter is directly electrically connected within the enclosure to the direct current input of said direct current to alternating current voltage source inverter.
