Power Quality Solutions

Active Harmonic Filter

Ecosine Active Harmonic Filter

Active harmonic filters are intelligent power quality devices that continuously monitor the 3-phase line current and dynamically provide a precisely controlled current spectrum for real-time suppression of harmonic distortions created by non-linear loads. Operating at the Point of Common Coupling (PCC), they facilitate compliance with all international Power Quality standards, e.g. IEEE 519 or EN 61000-3-12 and local regulations.

Features and benefits

  • Most effective harmonic mitigation up to the   50th order, parameter setting for even and odd   harmonics

  • Compact active harmonic filter for 3-phase    loads with and without neutral wire

  • THDi < 5%, achievable even on most complex   mixed loads and at changing load profiles

  • New modular design with intelligent system   approach – to offer tailored solutions for    different applications and customers

  • 3-Level IGBT inverter topology for reduced  power losses

  • Extended temperature range of modules up to 50°C

  • Ultra-fast and dynamic reactive power compensation (inductive and capacitive)

  • Load balancing and unloading of neutral wires

  • Available in 60A modules, up to 300A enclosed,   with parallel capability for higher ratings

Passive Harmonic Filter

Ecosine High Power Line

High Power Line Harmonic filter

Ecosine filters can be applied to virtually any kind of power electronics with front-end six-pulse rectifiers, where harmonic current distortion needs to be reduced to defined limits. The high power filter modules are particularly suitable when no room for packaged filters is available. Our solution can conveniently be incorporated into cabinets, which allow the filter components to be wired along with the overall electrical wiring job and to be cooled by jointly utilizing the overall cooling concept.

Typical applications include higher power AC and DC, motor drives with either six diode used e.g. in HVAC, water/wastewater, oil & gas, or mission critical factory automation equipment. In addition, ecosine filters can help to reduce thermal and electrical overload caused by harmonic currents in installations involving UPS, high power rectifiers and other non-linear threephase power supplies.
