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 helps you save
Since one module supports multiple drives, you can save space and ensure fl exibility 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.
When it comes to regulatory compliance, you need a solution you can depend on. But more than that, why not consider a solution that leaves room for growth? With ADF, you can remain care-free in the knowledge that this low harmonic solution will ensure you meet necessary standards. See some examples here:
Maintain your equipment warranties
With increasingly sensitive equipment, come stricter technical infrastructure demands and increasing electrical disturbances. Avoid this concern over loss of warranties with a stable and reliable power quality solution.
Extend your equipment lifetime
A reliable power quality solution ensures that unstable power is compensated. With ADF, you lower the risk for wear, expensive shutdowns, and replacement.
