Armature circuit interface
The function for the armature circuit interface consist of:
– Firing the armature bridge of 6 or 12 thyristors.
– High ohmic measurement of DC and AC voltages.
– Residual current measurement of armature circuit to ground
= 5 mA at 500 V supply (
1 M).
– Interface for the current transformers for current measurement.
– Snubber circuit for the thyristor protection together with R1 on the heatsink.
– Interface for heatsink temperature measurement with a PTC.
– Fuses for overvoltage protection and field circuit.
