Integrated gate-commutated thyristors (IGCT)
All ABB IGCTs (Integrated Gate-Commutated Thyristors) are press-pack devices. They are pressed with a relatively high force onto heat-sinks which also serve as electrical contacts to the power terminals. The IGCT's turn-on/off control unit is an integral element of the component. It only requires an external power supply and its control functions are conveniently accessed through optical fiber connections. The device's control power consumption typically ranges from 10 - 100 W.
Asymmetric IGCT devices are single devices optimized for snubberless turn-off operation. The associated recovery diodes can be chosen from our fast recovery diodes product range.
Reverse conducting IGCTs are monolithical integrated freewheeling diodes. They are optimized for snubberless turn-off conditions
