Product Description

The DC smoothing reactor is used in the rectifier circuit to suppress the ripple and pulsation components after rectification, make the rectified current continuous, improve the output tributary waveform, and ensure the normal operation of the DC equipment.

Application

1. Improve the input current waveform distortion caused by capacitor filtering.

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

3. Improve the power factor and reduce the DC bus AC pulse.

4. Limit transients in grid voltage.

5. Together with the capacitors connected in parallel, suppress or filter the ripple in the DC to eliminate the adverse effect on the load.
