APPENDIX 1 - TPD32-EV-CU: CONTROL UNIT
General description
The TPD32-EV-CU-… is an electronic control unit designed for use with one or more six-pulse two or four-
quadrant power bridge SCR AC/DC converters. It is supplied as a stand-alone unit for systems that already have
a power bridge.
The control unit regulates the armature voltage and current, generates SCR gate command signals and also con
-
tains a 40 A or 70 A field power supply circuit. It is suitable for power bridges connected to a 230 VAC to 690
VAC 50/60 Hz three-phase voltage supply. It interfaces directly with the three-phase power line, the armature
voltage and armature current, measured by two current transducers that must be included on the power bridge.
It covers armature currents ranging from 4 A
dc
to 20,000 A
dc
.
