Power Challenges in Digital Infrastructure

AI, cloud, and edge workloads demand precise, reliable power. Hidden inefficiencies, such as harmonics, transients, and poor power factor, quietly erode performance, raise cooling demand, and shorten equipment life.

Harmonic Distortion Overload

Non-linear GPU loads generate severe harmonics—up to the 50th order—distorting waveforms, overheating transformers, and risking IEEE 519 non-compliance. This drives higher PUE, shortens asset life, and spreads instability beyond the data hall.

Low Power Factor & Hidden Costs

Erratic, reactive loads push power factors down to 0.7–0.9, inflating current draw and triggering utility penalties. For large AI campuses, this can translate to millions in avoidable annual costs.

Sub-Millisecond Transients & Voltage Swings

AllReduce and synchronized GPU events create ±10% voltage fluctuations within microseconds, equivalent to multi-MW faults. These transients strain UPS systems, risk server crashes, and undermine operational resilience.

Envelope Fluctuations Undermine Reliability

High-frequency surges from GPU clusters create EMI/RFI, stress PDUs, and degrade network power quality. This limits scalability, affects hardware reliability, and makes meeting uptime and PUE targets harder.

XCT Energy's integrated power quality solution

Active Harmonic Elimination

XCT deploys advanced Active Harmonic Filters (AHFs) that dynamically inject counter-harmonic currents up to the 50th order. This restores waveform integrity, reduces transformer overheating, and brings sites into IEEE 519 compliance — even under rapidly varying GPU loads.

Power Factor Optimization

Our solutions correct reactive power in real time, stabilizing power factor close to unity. By lowering apparent power draw, facilities can unlock spare capacity in existing infrastructure, avoid utility penalties, and defer costly electrical upgrades.

Sub-Cycle Transient Stabilization

Using digital signal processing and ultra-fast response times, XCT filters smooth microsecond-scale voltage fluctuations triggered by synchronized compute events. This reduces stress on UPS systems, prevents nuisance alarms, and supports grid code compliance for high-density AI deployments.

Envelope Smoothing & EMI Suppression

XCT’s power-quality equipment mitigates high-frequency switching noise and envelope fluctuations, protecting downstream servers, PDUs, and networked infrastructure. The result: lower PUE, improved equipment reliability, and a more stable electrical backbone for critical compute operations.
