Abstract (en)
[origin: WO2018172309A1] The invention relates to an electrical DC voltage system which is coupled to at least one AC voltage network (1). A supply circuit (5) is used to convert three-phase AC voltage into DC voltage which supplies a DC voltage system. The latter contains devices (13, 14, 21, 23, 27, 22, 17, 19, 20) each having a decentralized precharge device (7). The invention also relates to a method for operating such an electrical DC voltage system on the basis of a voltage value applied to the busbar (12).
