3.2.2 Line supply unit (LSU)
The LSU is a 12-pulse rectifier that rectifies the AC line voltage and
supplies the DC link with electrical energy. An LSU is used with input
transformers and is available in various power ratings
The LSU allows two-quadrant operation and maintains the power factor at
0.95 in the whole operating range.
To achieve 24-pulse rectification or to increase the drive power, units with
the same power rating can be operated in parallel.
