The DC reactor, also known as the flat wave reactor, is mainly used in the dc side of the converter and has more applications in the general frequency converter. There is a current of alternating current in the reactor. Main purpose is to stack in the ac component on the dc current is limited to a specified value, keep the rectifier current continuous, reduce the current ripple value, improve the input power factor, and can suppress harmonic converter device.Its specific functions include:The change of input current waveform caused by capacitor filtering is improved.It reduces and prevents the rectifier bridge damage and capacitor overheating due to shock current.Improve the power factor and reduce the ac pulse of dc bus.To limit the transient voltage of the grid.
