REDUCCIÓN DE LAS OSCILACIONES ARMÓNICAS
EN EL CIRCUITO INTERMEDIO

Una reactancia de circuito intermedio alivia la carga de la red de alimentación
compensando la potencia reactiva de armónicos. 

De forma análoga a una reactancia de red, una reactancia de circuito intermedio actúa como componente pasivo y contribuye a reducir las oscilaciones armónicas y a aliviar la descarga de la red de alimentación. La reactancia de circuito intermedio también atenúa la corriente de carga de pico de los condensadores de circuito intermedio. Estas reactancias se emplean en convertidores de frecuencia en las aplicaciones de la técnica de accionamiento y alimentación de corriente de CC de carácter general.

  • CNW 891

    Single-phase DC-link choke (1 lines)

    CNW 891
    • Tensión nominal: 600 V
    • Corriente nominal: 8 - 100 A
    • Inductancia: 0,67 - 9,4 mH

    Power Noise Reduction - save energy costs. 


    The DC-link choke is used for smoothing the DC link current and to reduce mains harmonics in voltage source inverters.


    The typical combinations of rectifiers and capacitors strains the supply network significantly. For functional reasons, the current consumption of the power supply or the inverter is not sinusoidal but pulsed at the moment of maximum voltage. DC-link chokes reduce the harmonics and relieve the supply network similar to the mains choke. In addition, the DC-link choke attenuates charging current peakssurges of the DC-link capacitors. By using a DC-link choke the supply network is less burdened with harmonic reactive power.


    Improvement of the efficiency of a converter (Power Factor Correction). Starting currents and current peak are attenuated up to 70%. Mains chokes help to comply with international power quality standards IEEE 519 or EN 61000-3-2.
