Wich inverters are used for the new H200 datacenters? How much percent of total cost?

Inverters Used in H200 Datacenters:

The NVIDIA H200 GPU is typically deployed in hyperscale datacenters, often within high-density AI clusters. These datacenters predominantly use three-phase, high-efficiency, uninterruptible power supply (UPS) inverters. The most common inverter technologies in these environments are:

• IGBT-based (Insulated Gate Bipolar Transistor) inverters for large-scale, centralized UPS systems (typically 500 kVA and above).
• Modular, transformerless double-conversion UPS systems (e.g., Schneider Electric Galaxy VX, Vertiv Liebert EXL S1, Eaton 93PM), which use advanced silicon-based or sometimes SiC (Silicon Carbide) MOSFET inverters for improved efficiency and reduced footprint.

Specific Inverter Models:

• Schneider Electric Galaxy VX (uses IGBT inverters, 500 kVA+)
• Vertiv Liebert EXL S1 (IGBT, up to 1200 kVA)
• Eaton 93PM (IGBT, modular, up to 500 kVA)
• Huawei UPS5000-E (modular, transformerless, IGBT)

Inverter Role and Sizing:

• Each power block (typically 1-2 MW) is backed by a UPS with inverters sized for the full IT load plus overhead.
• H200 clusters require extremely stable power, so inverter-based double-conversion UPS is standard.

Cost Proportion of Inverters in Total Datacenter Build:

• UPS (including inverters) typically accounts for 7–12% of total datacenter capital expenditure (CapEx).
• The inverter module itself is a subset of the UPS cost, but in industry cost breakdowns, the entire UPS (rectifier, battery, inverter, controls) is grouped together.
• For a high-density AI datacenter (e.g., H200-based), power infrastructure costs are higher due to increased power density, but the inverter/UPS share remains within the above range.

Example Calculation (per $100M datacenter build):

• Total electrical infrastructure: ~25–30% of CapEx
• UPS systems (with inverters): ~8–10% of CapEx ($8M–$10M per $100M build)
• Inverter hardware alone: ~3–4% of CapEx (since inverter is a major but not sole UPS component)

Edge Note:
For hyperscale AI datacenters, inverter/UPS selection is driven by power density, efficiency (>96% typical), and modularity for rapid scaling. SiC-based inverters are emerging for even higher efficiency but are not yet standard in most deployments as of 2024.
