ADF Power Tuning

ADF Power Tuning – the shape of power to come!


Power isn’t perfect

The advanced technology and heavy processes of today’s industry put high demands on the electrical grid and make operations vulnerable to a variety of problems.

  • Overheating transformers
  • Nuisance tripping
  • Non-compliance
  • Shorter equipment lifetime
  • Production failure/downtime
  • Exceeding norm limits

These problems are caused by a variety of electrical disturbances that weaken power quality.

What are you Paying for Poor Power Quality?

Improving power quality reduces risk, raises throughput, decreases the cost of doing business, and improves your bottom line.


For support with making a decision for your facility, don’t hesitate to contact us.


The best solution to poor power quality

ADF Power Tuning products eliminate common electrical behaviors that contribute to poor power quality. By using a highly dynamic, digitally controlled compensation and filtering approach, ADF Power Tuning restores the current waveform instantaneously, lowers the current flow, and fully compensates changes in load or installation conditions at all times.

Active Dynamic Filtering

Our patented Active Dynamic Filtering technology offers unparalleled harmonic compensation, resonance mitigation, and much more. For a thorough presentation of ADF technology and its capabilities, explore our Technology pages.

Avoid downtime and achieve compliance

Common electrical disturbances and more can be solved with ADF Power Tuning solutions. Not to mention, ADF technology can assure power quality compliance and protect equipment warranties.

Data Sheets found here.

An ADF unit is basically a very advanced computer-controlled current generator with the ability to instantly produce any shape or form of compensation current.

A simplified diagram of the ADF operating principle is shown in the figure below.


Each ADF unit is connected in parallel, in shunt, with the load that requires compensation. The power flows of electrical currents between the load and the network are measured and analyzed [ 1 ] to determine if disturbances such as reactive displacement and/or harmonics are present.

If found, the ADF unit injects phase currents [ 2 ] that are the exact opposite of, for example, the harmonics and/or reactive displacement. This is done in order to cancel out the load behavior [ 3 ].

The result is an ideal load with a minimum of power losses and disturbances. The energy profile then appears ideal to the transformer.

ADF Power Tuning helps you save:


Since one module supports multiple drives, you can save space and ensure flexibility for the future.


Increase energy efficiency while reducing the expense of replacing worn equipment.


Avoid unnecessary downtime for maintenance or replacement of equipment affected by power quality issues.


ADF-type technology is already being included in regulatory demands and equipment warranties — a trend that will only continue to grow.
