Thyristors
High-power thyristors are used in applications ranging from 100 kW drives up to HVDC stations rated above 10 GW.
Since many applications use antiparallel connected thyristors, we introduced the bi-directionally controlled thyristor (BCT), which consists of two integrated antiparallel thyristor functions on one silicon wafer.
Hitachi ABB Power Grids offers the following thyristor
families:
• Bypass thyristor
• Phase control thyristors (PCTs)
• Bi-directionally controlled thyristors
(BCTs)
