Description

technical field

[0001] The invention relates to a rectifying device, in particular to a green energy-saving DC power station. Background technique

[0002] At present, DC power stations with AC-DC power electronic conversion devices generally have problems such as serious harmonic pollution, low power factor, low operating efficiency, and high working noise, which will inevitably cause a certain degree of waste of electric energy and bring economic benefits to enterprises. Negative impact. Moreover, the harmonic current disturbs to the power grid side, which will also cause certain pollution to the power grid and affect the safe and economical operation of the power grid. There are mainly two traditional methods for solving the above problems. One is to adopt a multiple rectification scheme, by adding a phase-shifting transformer, or configuring a phase-shifting winding on the primary side of the rectifier transformer, to achieve 12, 18, 24 or even higher 48-pulse multiple...
