Why the industry is exploring 800 VDC
Challenges
Power delivery consequence
Rising rack densities
▶
AI rack densities ~350-400 kW and beyond require new distribution architectures.
Increasing current
▶
Larger conductors and infrastructure
Loss of compute space
▶
Power equipment consumes valuable rack capacity
AI load variability
▶
Greater demands on electrical infrastructure
Power management optimization
▶
Better grid interaction, safety architecture, and the ability to scale without redesigning the power backbone
