Data Center Power Infrastructure

Why AI infrastructure is changing data center power

AI infrastructure is changing how data centers are powered. Higher rack densities, faster load swings and the move toward 800 VDC are pushing AC/DC conversion upstream and making storage integration a core part of facility design.

AI data center building

KraftPowercon supports this shift with products suited to multiple points in the emerging 800 VDC power chain — from facility-level rectification to controlled DC-side energy integration.

Key proof points for the 800 VDC shift

+157%
More power through the same copper
800 VDC enables significantly more power transfer through the same conductor cross-section compared with 415 VAC.

~1.5 MVA
Typical facility rectifier string
Facility-level AC/DC rectifiers are a practical architecture step for delivering stable 800 VDC from low-voltage AC.

Core
Energy storage is not optional
AI load behavior makes storage integration part of the architecture, not just an add-on for backup.

From retrofit path to facility-level 800 VDC

Stage 1: 415 VAC distribution architecture
Step 1
415 VAC distribution
The starting point is the conventional 415 VAC approach, where AC distribution and conversion are handled close to the rack. It is familiar and deployable today, but it also keeps more conversion hardware and complexity in the white space.
Step 2: 800 VDC side power rack architecture
Step 2
Side power rack
A practical near-term step is to move AC/DC conversion out of the compute rack into a dedicated side power rack. This supports higher rack density while minimizing disruption to existing white-space layouts.
Step 3: facility-level 800 VDC backbone architecture
Step 3
Facility-level 800 VDC backbone
The stronger long-term architecture is to place rectification upstream and create a common 800 VDC backbone. That reduces rack-level conversion complexity and creates a more direct path for integrating storage, grid interaction and resilient operation on the DC side.

Why builders are moving toward 800 VDC

Higher rack power without bigger copper burden
As AI racks move toward much higher power density, traditional 415/480 VAC distribution becomes harder to scale cleanly.

Fewer conversion stages
Moving conversion upstream simplifies the power chain and frees valuable space closer to the compute hardware.

Better fit for dynamic AI loads
Synchronized GPU workloads create fast load swings that require a power architecture with stronger control and storage integration.

Where KraftPowercon fits in the 800 VDC architecture

The new 800 VDC architecture is not one product. It is a power chain. KraftPowercon brings relevant products and industrial DC conversion experience to key parts of that chain — especially upstream AC/DC conversion and DC-side energy integration.

iKraft
Modular rectification platform suited to facility-level AC/DC conversion for an 800 VDC backbone, with a strong fit for scalable high-power deployment.

DCKraft
Controlled, galvanically isolated DC/DC integration for batteries and other DC-side energy assets connected to the 800 VDC system.

Industrial DC know-how
Experience from high-power rectification and DC integration markets that are directly relevant to the direction AI data center power is taking.

Built for dynamic AI loads and storage integration

AI workloads are not static. GPU clusters can create fast and synchronized power swings that affect not only the rack but the facility and the grid connection.

That is why energy storage is becoming part of the architecture itself. Facility-side storage can support load averaging and grid interaction, while faster local storage helps absorb short-duration events closer to the compute load.
