What You're Running.

Modern GPU clusters create millions of multi-megawatt surge-and-sag events every month. Triplen harmonics flood neutral conductors, transients reflect back from idle GPU states, and existing mitigation only works on the supply side.

The Problem

Why AI Workloads
Break Infrastructure

GPUs don't draw power steadily. They surge, idle, surge again, millions of times per day. Each cycle creates a cascade of electrical consequences that existing solutions were

  • Multi-Megawatt Burst Events
    Modern GPU clusters draw and release 3–30 MW bursts in under one second, repeating thousands of times per hour.
  • Return-Side Chaos: The Unsolved Problem
    Conventional APFs, SVGs, UPS, and BESS systems work only on the supply side, reacting after distortion appears.
  • Infrastructure Fatigue at Accelerating Rate
    Repetitive sub-cycle load ramps overwork UPS and BESS converters, shortening their life by 20–30%. Transformers derate under harmonic heating.
  • Energy Waste Hidden in Plain Sight
    Nonlinear GPU load response increases system losses by 3 to 8%, raises PUE, and amplifies cooling load, a compounding cost at scale. Eddy current losses driven by harmonic distortion add a further 2 to 3% in transformer cores and motor laminations, invisible on standard metering but measurable under Class A instrumentation.

The Blind Spot

Every Competitor
Misses The
Return Side

APFs treat supply-side harmonics. UPS handles outages. BESS smooths demand. None of them address what happens after current leaves the GPU and flows back through neutrals and negative buses.

AC Side
Triplen Harmonic Flooding
Triplen harmonics — the 3rd, 9th, 15th, 19th, and 21st orders — generated by GPU switching add up constructively in the neutral conductor rather than cancelling. Unlike other harmonic orders, triplens are mathematically additive across all three phases, making neutral flooding unavoidable without active cancellation.
Consequence
Neutral overheating · transformer derating · voltage drop
DC Side: 800V Bus
GPU Idle Reflection
When GPU clusters transition from active inference to idle state, excess stored energy in the 800V DC bus doesn't simply disappear, it reflects upstream as voltage swells and transients.
Consequence
UPS/BESS life shortened 20–30% under repetitive cycling
Frequency Domain
ROCOF Grid Instability
Sub-second load changes, happening thousands of times per hour, disturb the 60 Hz balance and create Rate-of-Change-of-Frequency (ROCOF) issues in low-inertia grid connections.
Consequence
Grid penalties · frequency deviation · oscillation risk
Infrastructure
Compounding Fatigue Cycle
Each individual event is manageable. The problem is the rate: millions per month, consistently stressing the same components. Thermal cycling compounds insulation degradation.
Consequence
I²R losses +2–3% · 3–8% kWh waste · higher PUE
The Solution

Simultaneously.

The Electrical Current Balancing System is the only solution that addresses both supply and return sides of the power network in real time

Network Envelope Smoothing
Reduces GPU power peaks by ~20%, lowering PUE and thermal strain. Smooths the burst profile so downstream infrastructure sees a consistent load rather than violent millisecond
~20% peak reduction · lower PUE + cooling load

Protecting The
Infrastructure You
Just Bought

GPU clusters are the revenue engine. But the transformers, UPS, BESS, and switchgear surrounding them represent tens of millions in capital that degrades silently under every workload spike.

01 / 05
UPS Systems
ECBS eliminates the repetitive sub-cycle ramps that force UPS converters to respond thousands of times per hour. By delivering a preconditioned, stable waveform, Xeco also improves UPS cycle times, reducing the frequency and depth of each charge/discharge event and extending converter life.
95% fewer UPS/BESS events · improved cycle times · 20–30% life extension
02 / 05
Transformers
Triplen harmonics accumulate in neutrals and cause transformer overheating, the leading cause of premature transformer failure in GPU-heavy facilities.
80% less heating · +30–50% transformer lifespan
03 / 05
BESS Systems
Battery energy storage converters are among the most sensitive components in a modern data center power stack. Voltage swells from GPU idle states trigger unnecessary charge/discharge cycles.
Clean waveforms for BESS · extended battery cycle life
04 / 05
Switchgear & PDU
PDUs sit closest to the GPU rack loads and absorb the worst of each surge-and-sag cycle, experiencing greater voltage fluctuation than upstream switchgear. Voltage swings of 10 to 15% at the PDU level cause arcing in contactors and breaker contacts, accelerating mechanical wear. Upstream switchgear sees fewer transient spikes but still accumulates fatigue from repetitive fault events over time.
±1–2% voltage · 80% arcing reduction
