SOL represented in the CFC
The switch-over logic stage FB–SOL (Switch Over Logic) controls the
sequence when switching-in and switching-out the closed-loop thyristor
current control for:
•
4Q drives with drive converters in a circulating current-free anti-
parallel circuit configuration comprising two fully-controlled three-
phase bridge circuits
•
1Q drives with drive converter in a fully-controlled three-phase bridge
circuit configuration.
