Parallel connection of double three-phase bridge rectifiers
Conditions: α=0, Ld=∞, La=0
                                                                    
Figure 1.44
Line voltages of transformer are displaced on 30 degrees due to connection of transformers of the first bridge - Y/Y, the second - ∆/Y.
The principle of operation is similar to double three-phase star with the current-balancing reactor (CBR). CBR takes up a difference of variable components ed1 and ed11.

For double three-phase bridge with CBR
Hence, typical power CBR is insignificant.
