Effective active filters for a stable power supply

PQ ENGINEERING offers a wide range of active filters – from compact 30 A harmonic filters in wall-mounted enclosures to modular cabinet systems with rated voltages up to 690 V. We specialize in the latest generation of voltage-controlled filters.

Protect your power grid and operational processes from critical grid disturbances with an active filter from PQ ENGINEERING:

✔ Harmonics
✔ Inductive and capacitive reactive power
✔ Grid asymmetries
✔ Resonance effects
✔ Flicker interference

Active harmonic filters are divided into current-controlled filters, which can selectively and dynamically compensate multiple harmonics simultaneously, and voltage-controlled filters. The latter also enable broadband filtering of harmonics and supraharmonics. The challenge of reducing rapid voltage fluctuations (flicker) is easily overcome.

Advantages of voltage-controlled filters

Why only measure current harmonics when voltage distortions need to be compensated?

Voltage-controlled active filters are able to To specifically reduce harmonics and interharmonics of the voltageDue to their mode of action, they can work impedance-controlled and so active Dampen resonances.

PQ ENGINEERING offers active mains filters in all power ranges from well-known manufacturers In addition to the current-controlled active filters that are widely used on the market, active filters with voltage regulation our specialty.
