Interfacing the Electronics and Thyristors

The connection shown below is used normally when the anti parallel bridge is built
by connecting two mechanically separate bridges in an anti parallel configuration.
Then gate wiring is most simple and short when all six thyristors of a bridge are
connected to one pulse transformer board.

4-quadrant application, no parallel thyristors
Connection for 4-quadrant application - parallel thyristors
With parallel connected thyristors, both additional boards
SDCS-REB-1 and SDCS-REB-2 are needed. Because of the REB-2 board exter-
nal +24V and +48V are needed. The power supply SDCS-POW-4 is not able to
give enough power for parallel connected thyristors.
The figure below shows the configuration for a 4-quadrant bridge with 4 parallel
connected thyristors.
