DC flat wave reactor
The DC smoothing reactor is used in the rectifier circuit to suppress the ripple component after rectification, and to make the rectifier current continuously.
Improve the output waveform and ensure the normal operation of DC equipment.
Characteristics and advantages
1. improve the input current waveform distortion caused by capacitor filtering.
2. reduce and prevent damage caused by impact current and overheat of capacitor.
3. increase power factor and reduce DC bus AC pulse.
4. limit the transient voltage of the power grid.
5., a parallel connection capacitor is used to suppress or filter ripple in DC to eliminate the adverse effects on the load.
