BCT thyristors
In some converter modules size D6 so called BCT’s (Bidirectional-Controlled-
Thyristors) are used. BCT’s are a pair of anti-parallel thyristors in one disk type
housing. They can easily identified by the second pair of gate leads. The second
gate is marked with Gate B on the thyristor.
