Phase controlled thyristors for lower operating frequency. Fast thyristors with guaranteed turn-off time designed for circuits of self-commutated converters. Reverse conducting thyristors (RCT) with optimised rate of thyristor and diode area. GTOs, typical with low forvard and turn-off losses. IGCT thyristors with ultra-fast turn-off process. RCTs, GTOs and IGCTs are applicable especially for traction.
