LV Iron Core Smoothing Reactors

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

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

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

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