Description
Consists of integrated gate-commutated
thyristors (IGCTs), diodes and clamp capacitors.
The phase modules are identical in construction
for all power ratings. However, the types of
semiconductors vary depending on the power
rating. For this reason, it is not possible to mix
phase modules for different power ratings in one
unit.
Protects the circuit from excessive rises in current
with di/dt reactors and freewheeling diodes.
Protects the transformer from excessive
voltage slopes
