How AmpMiner® Works
Parallel-passive electromagnetic field effect conversion
A technical deep-dive into harmonic recycling and I²R loss recovery from stray current
The Hidden Energy Loss Problem
Where Power Gets Lost
Modern electrical systems experience three primary categories of recoverable losses:
1. Harmonic Distortion
Non-linear loads (VFDs, switch-mode power supplies, LED drivers) create harmonic currents that circulate without doing useful work—heating conductors and transformers.
2. Reactive Power (VARs)
Inductive and capacitive loads cause current and voltage to fall out of phase, reducing power factor and wasting distribution capacity.
3. I²R Losses from Stray Current
Leakage currents and non-fundamental frequency components create resistive heating losses in conductors and neutral paths—AmpMiner recovers these I²R losses associated with stray current.
Industry Impact
These losses compound across the grid:
Most facilities accept these losses as "unavoidable overhead." AmpMiner proves they're recoverable.

The Science: Field Effect Conversion
How magnetic field manipulation converts reactive and distorted power into true power at the fundamental frequency
Nano-Crystalline Magnetic Field Manipulation
AmpMiner® leverages nano-crystalline doped amorphous common-mode chokes in a proprietary configuration to convert reactive and distorted power components into true power through a four-step electromagnetic process:
1. Quasi-Common-Mode Array Engagement
The passive array engages odd harmonic field activity at the return-path (neutral/ground), capturing distorted electromagnetic energy that would otherwise circulate as waste heat in conductors and transformers.
Unlike traditional common-mode chokes that simply block noise, this proprietary quasi-CM array actively intercepts and routes harmonic magnetic fields for conversion.
2. Waveguide Routing & Cancellation
Captured harmonics are routed into a custom-engineered magnetic waveguide where they undergo selective cancellation and field reshaping—analogous to noise-canceling technology, but operating on electromagnetic fields rather than acoustic waves.
The waveguide architecture uses controlled flux paths to separate and process different harmonic orders, enabling targeted conversion without affecting the fundamental frequency.
3. Fundamental Frequency Conversion
The distorted magnetic field is reshaped into a phase-corrected fundamental waveform at 60Hz (or 50Hz for international applications), converting previously unusable harmonic energy into clean, usable AC power at the grid frequency.
This step represents the core innovation: rather than dissipating harmonic energy as heat (passive filters) or canceling it with opposing currents (active filters), the system converts the frequency domain of the energy itself.
4. Upstream Redistribution
The localized harmonic-to-fundamental conversion facilitates real-time magnetic field redistribution and phase rotation corrections across the upstream Wye-side transformer supply, while actively improving every known parameter of power quality downstream.
This creates a cascading benefit: improved transformer efficiency, reduced neutral leakage, balanced phase currents, and enhanced power delivery to connected loads.
Key Innovation: Conversion, Not Just Mitigation
Unlike conventional harmonic filters that dissipate energy as heat (passive) or require power input to generate canceling waveforms (active), AmpMiner® converts and recycles that energy back into the panel as usable capacity—representing a fundamental paradigm shift in power management from loss mitigation to energy recovery.
Understanding Common-Mode vs Differential-Mode
Electronic equipment is 10 to 100 times more sensitive to common-mode noise than differential-mode noise. This fundamental difference drives the FEC architecture:
Common-Mode Current
Flows in the same direction through all conductors, using ground as return path. Created by high-frequency switching, parasitic capacitance, and EMI propagation.
Differential-Mode Current
Flows in opposite directions through conductors (normal operation). Traditional power factor correction addresses differential-mode reactive power.
Inverse Relationship
As EMI increases, stray currents converge on phases and diverge from neutral—FEC corrects this imbalance while recovering the associated I²R losses.
Cold-Side Installation Advantage
AmpMiner® operates on the "cold side" of the electrical panel (neutral/ground only), providing critical deployment benefits:
Zero Downtime
No "hot side" connections required—installation without service interruption
Magnetic Buffer Function
Intercepts and converts noise to fundamental frequency (60Hz) through selective attenuation
Safety & Compliance
UL 1283 and CSA certified for commercial deployment with N/G terminations only
Harmonic Recycling vs. Harmonic Mitigation
Traditional Harmonic Filters
Conventional active and passive filters block or cancel harmonics:
- • Passive filters: shunt harmonics to ground (wasted as heat)
- • Active filters: inject opposing waveforms (requires power input)
- • Result: cleaner waveform, but energy is dissipated
- • No capacity recovery—just mitigation
AmpMiner Harmonic Recycling
AmpMiner converts and recovers harmonic energy:
- • Captures stray EM fields from harmonic currents
- • Converts non-fundamental frequencies back to 60Hz AC
- • Returns recovered power to the panel as usable amps
- • Result: cleaner waveform plus capacity gains
✓ AmpMiner is the only solution that both mitigates harmonics AND recovers the energy

Frequently Asked Questions
Can AmpMiner work alongside existing harmonic filters?
Yes. AmpMiner is designed to complement passive and active filters. While traditional filters block or cancel harmonics, AmpMiner recovers the energy—providing both power quality improvement and capacity gains.
How is this different from power factor correction?
Power factor correction addresses reactive power (VARs) using capacitor banks. AmpMiner goes further by also recovering harmonic distortion energy and I²R losses from stray current—energy that PFC alone cannot capture.
What kind of savings can I expect?
Typical deployments see 5–20% reduction in effective load, depending on harmonic content and load profile. We provide a 90-day trial with third-party M&V to measure your specific savings before you commit.
Does installation require downtime?
No. AmpMiner units are installed in parallel and can be hot-swapped without interrupting service.
