LV Iron Core Smoothing Reactors

Smoothing Reactors are serially connected reactors inserted in DC systems to reduce harmonic currents and transient over currents and/or current ripples in DC systems.

They are necessary in order to smooth the direct current wave shape to reduce losses and improve system performance.

Smoothing Reactors reduce the occurance of alternation failure in inverters caused by the dips in AC voltage at the converter bus. They prevent consequent communication failures in inverters by reducing the rate of rise of direct current in the bridge when the direct voltage of another series connected bridge collapse.

Smoothing Reactors smooth the ripple in the direct current in order to prevent the current becoming discontinous for light loads. They decrease harmonic voltages and currents in DC lines. They limit the crest current in the rectifier due to a short circuit on the DC line.
