AC-commutated static converter circuit - has diodes and circuit turning thyristor off independently of input voltage

The AC-commutated static converter has the main thyristors in its bridge turned off independently of the input voltage of the converter. There is a series circuit comprising a shared turn-off circuit (5) (with turn-off thyristors (51-54) and a turn-off capacitor (55) in one bridge diagonal). There i...

Zusammenfassung:The AC-commutated static converter has the main thyristors in its bridge turned off independently of the input voltage of the converter. There is a series circuit comprising a shared turn-off circuit (5) (with turn-off thyristors (51-54) and a turn-off capacitor (55) in one bridge diagonal). There is a distribution diode (1, 2) which is connected in parallel with the main thyristors (8, 9). The distribution diodes are poled in the same conduction sense as the turn-off thyristors.
