Interfacing the Electronics and Thyristors
3ADW000197R0101 DCS800-R Sel e a
Connection for 4-quadrant application – No parallel Thyristors
There are three ways shown on the next three figures, how to connect the thyris-
tors, the pulse transformer board(s) and the measuring board to each other.
At figure below the flat cables are connected between
SDCS-PIN-51 X113 to SDCS-PIN-48 X113 and
SDCS-PIN-51 X213 to SDCS-PIN-48 X213,
which gives the result, that
- one SDCS-PIN-48 board transfers all the firing pulses for the thyristors, con-
nected to D1 (see figure Arrangement of thyristors in an anti parallel bridge)
- the other SDCS-PIN-48 board transfers all the firing pulses for the thyristors,
connected to C1 (see figure Arrangement of thyristors in an anti parallel bridge)

Firing pulse assignment
At figure below the flat cables are connected between
SDCS-PIN-51 X413 to SDCS-PIN-48 X113 and
SDCS-PIN-51 X313 to SDCS-PIN-48 X113,
which gives the result, that
- one SDCS-PIN-48 board transfers all the firing pulses for the thyristors, con-
nected to phase L1 and half of the thyristors, connected to phase L2 (see fig-
ure Arrangement of thyristors in an anti parallel bridge)
- the other SDCS-PIN-48 board transfers all the firing pulses for the rest of the
thyristors, connected to phase L2 and for the thyristors, connected to phase L3
(see figure Arrangement of thyristors in an anti parallel bridge)
