AI RACK DENSITY • Scale-up requires tightly coupled compute • Power, cooling and networking compete for space • Low-voltage AC faces current, copper, heat, and space limits 120 140 240 600
p4
MORE COMPUTE The Shift DC • Fewer conversions • Higher power density • Smaller footprint 800 V • At same power 16× less current 256× less power losses Less copper Less heat
p5
How do we enable DC ? ..an architecture is needed SOLID STATE TRANSFORMER MVAC/800Vdc LOCAL DISTRIBUTION TO RACKS MAIN POWER DISTRIBUTION 800Vdc 800Vdc, +/- 400Vdc GRID 34.5kVac
