IGCT
Integrated gate-commutated thyristors (IGCT) are used as switching devices in the
inverter section of the phase converter units. IGCTs combine fast switching
capabilities with low losses and enable a drive design with a low parts count.

Fuseless protection concept
The drive does not require any power fuses. Instead, the IGCTs of the inverter are
used for protection. If an overcurrent occurs, protection firing is triggered and
fault clearing is initialized in less than 25 µs.
