Power distribution system

A voltage distribution system, comprising:

• an Information Technology (IT) rack comprising:
• an enclosure body having a vertical bus bar and a plurality of rack slots, the vertical bus bar being configured to receive power from a voltage distribution bus bar, each rack slot from among the plurality of rack slots configured to house a respective node and a corresponding sidecar unit for the respective node;
• and
• a sidecar unit comprising:
• a body configured to be housed, together with and adjacent to a node, in a rack slot of the IT rack;
• an input connector coupled to the vertical bus bar, the input connector configured to receive, from the vertical bus bar, input power having a first voltage;
• a converter that converts the input power from the first voltage to a second voltage, which is lower than the first voltage, to generate output power, or a bridging module that provides the output power in the first voltage;
• and
• an output connector coupled to the adjacent node in the rack slot, the output connector configured to provide the output power to the corresponding node,
• wherein the sidecar unit is configured to be releasable from the node to facilitate servicing the sidecar unit and/or the node.

A voltage distribution system, comprising:

• a power rack comprising:
• one or more power supplies that provide High Voltage Direct Current (HVDC) power in a range of at least 400V;
• and
• a first vertical bus bar electrically coupled to the one or more power supplies and to a voltage distribution bus bar, the first vertical bus bar electrically transmitting the HVDC power from the one or more power supplies to the voltage distribution bus bar;
• an Information Technology (IT) rack comprising:
• a plurality of rack slots, each rack slot configured to receive a node and corresponding sidecar unit;
• and
• a second vertical bus bar electrically coupled to the first vertical bus bar to receive input power from the first vertical bus bar and distribute the input power to one or more equipment housed in at least one of the plurality of rack slots;
• and
• a sidecar unit comprising:
• a body configured to be housed, together with and adjacent to a node, in a rack slot of the IT rack;
• an input connector coupled to the second vertical bus bar, the input connector configured to receive, from the second vertical bus bar, input power having a first voltage;
• a converter that converts the input power from the first voltage to a second voltage, which is lower than the first voltage, to generate output power;
• and
• an output connector coupled to the adjacent node in the rack slot, the output connector configured to provide the output power to the corresponding node, wherein the sidecar unit is configured to be releasable from the node to facilitate servicing the sidecar unit and/or the node.
