① SA Source

Context Before

Hence, HVDC (high voltage direct current) power rack, BBU (battery back up units), CBU (capacitor backup units), liquid cooled busbar, and SST (solid state transformers) are being developed to increase transmission efficiency and power stability. These will be deployed by customers depending on their proprietary infrastructure designs.

Evidence

For the VR NVL72 reference design, the power delivery infrastructure at the rack level includes four 110kW power shelves.

Context After

The VR NVL72 system has a TDP up to 220kW for the 2300W Rubin TDP SKU. The design with four 110kW power shelves is an N+1 redundancy approach. Each 110kW power shelf is 3U tall and includes six 18.3kW PSU with built in capacitors in the PSU. Each power shelf receives three phase 415VAC-480VAC of power from two 100A whips.
