Passive harmonic filters offer cost-effective harmonics mitigation

By eeNews Europe


The devices close the gap between full-performance filters and simple reactor-based solutions. They are particularly suitable for applications where available space is scarce and a cost-effective solution for harmonics mitigation is required. By using the new passive harmonic filters, every standard AC or DC motor drive can be easily upgraded to a low harmonic drive. The filters offer a compact and more cost-effective alternative to the existing full-performance filters (THID <5%) and are particularly suitable for applications where harmonics mitigation to less than 10-15% is sufficient. Rectifier peak current and RMS input current are both reduced and a sine wave-like current is drawn from the grid. Lower electrical losses result in thermal unloading and allow for a better utilization of electrical system capacity.

The required filter rating can easily be determined based upon the nominal power rating of an individual non-linear load or a group of such loads. Cabinet integration next to the motor drive has now become even easier with the substantially smaller filter package. Furthermore, the user-friendly filter concept allows for a quick installation, wiring and commissioning without the need of thorough system analysis and the involvement of specialists. The ECOsine filters come in two versions: FN3416 filters for 380-500V, 50Hz grids, available with standard ratings from 4 to 160kW. And FN3418 filters for 380-480V, 60Hz grids, available with standard ratings from 5 to 250HP. All filters are UL-listed, CE-marked and RoHS compliant. They are particularly suitable for AC and DC motor drives, battery chargers and further power electronics with balanced 6-pulse input rectifiers.
