4.1 Twelve–pulse serial/sequential hardware configurations
The following figures show the most significant features of the 12 –
pulse
serial/sequential hardware configurations (max. output voltage
1600 V DC) with two DC thyristor power converters of the
DCS 600 se-
ries combined with the corresponding 12 – pulse control structures:
• Connection of converters in serial (sequential) configuration
• Master / Follower link [channel 2 on SDCS-AMC-DC boards]
• Master / Slave 12 – pulse communication link [channel V260 on
SDCS-CON-2 boards]

In this combination speed, current and field control are performed by
the 12 – pulse master. The 12 – pulse link control directs the firing
angle of the slave.
