Supply system for precharging of a d-c voltage network with electrical energy from an ac voltage network

摘要

The present invention relates to a supply system for precharging of a d-c voltage network (1) with electrical energy from an ac voltage network (10). In order to the dc voltage network (1), which is fed from an active feeding circuit, must be precharged, without these bank specifically to the configuration of the d-c voltage network (1) has to be designed, it is proposed that an active rectifier (20) on the input side with the alternating current power network (10) and on the output side to the dc voltage network (1) is connected, a preloading device (30) on the input side with the alternating current power network (10) and on the output side to the dc voltage network (1) is connected and the preloading device (30) a bridge circuit (31) comprises a line-commutated rectifier.
