DC Smoothing Reactor

Product Details

DC smoothing reactor is used in the rectifying circuit to restrain the ripple pulse component after rectification and make the rectified current continuous, so as to improve the output branch waveform and guarantee the normal operation of DC equipment.

The smoothing reactor is used as the series reactor in DC machine supplied by the converter, in order to eliminate the DC link in the current and voltage DC link converter; It is supposed to decouple the converter components on DC side. The power converter on DC side has high pulse circuit feedback to reduce the difference value limit, so as to limit the ring current on the connection with ring current, at the same time, limit the the rising rate of current. The smoothing reactor adopts the iron core of TEM and TET or TPK air core reactor, depending on the requirements on electromagnetic induction.

Product Application

Improve the input current waveform change caused by capacitor filtering.

Reduce and prevent rectifier bridge damage and capacitor overheating caused by impulse current .

Improve the power factor, reduce AC pulse of DC bus.

Limit the transients of power grid voltage.

Together with the parallel connected capacitor, they jointly suppress or filter the ripple in DC to eliminate the adverse effects on the load.
