2.13.5 Interbridge Transformer For DFE Drives
When using DELTA rectifier modules in a 12-pulse DFE drive, it is mandatory that an interbridge transformer
replaces the d.c. link inductor. In addition to performing the same functions as a d.c. link inductor, the
interbridge transformer forces sharing between the two rectifier bridges (one supply phase-shifted by 30°).
These naturally ventilated transformers are used with 12 pulse input rectifier systems - see Table 2-14.
