Design of the thyristor modules
Modules with six arms (B6C connection) are used for the converter. The thyristors in the
modules of system 2 are arranged in a mirror image to the thyristors in the modules of system 1.
Clamped thyristor stack for number of thyristors connected in series 1, 2 and 4
The clamped thyristor stack comprises x thyristors
④
in "press-pack enclosure" and x
+1 heatsinks

in such a way as to achieve the required contact force. The purpose of the heatsinks
is to dissipate heat losses.
