Context Before

Since the deployment of GB200, the main theme of the power delivery infrastructure evolution has been about transmission efficiency and power stability. Hyperscalers are developing power delivery infrastructure to address the challenges that comes with high density AI server racks with the roadmap set to 1MW per rack in the next couple of years.

Evidence

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.

Context After

These will be deployed by customers depending on their proprietary infrastructure designs.

② Atomic Claim

因此，HVDC power rack、BBU、CBU、liquid-cooled busbar 與 SST 正被開發，用來提高 transmission efficiency 與 power stability。
