Single-phase filters for field supply
Many field supply units are single-phase converters for up to 50 A excitation current.
They can be supplied by two of the three input phases of the armature supply
converter. Then a field supply unit does not need its own filter.
If the phase to neutral voltage shall be taken (230 V in a 400 V line) then a separate
filter is necessary. ABB offers such filters for 250 V and 6...30 A.
