Title: Thyristor column

Abstract: The invention concerns a thyristor column with disc thyristors which are stacked on top of each other and are mounted resiliently. A heat sink, which serves simultaneously as a conductor of electric current, is interposed on each side of each disc thyristor. Between the heat sinks of succeeding disc thyristors, a spacer element is inserted, on which ferrite cores are lined up. In this embodiment, the transient current is limited by the choke formed by the spacer element and the ferrite cores. The resistors of the external R-C components can therefore be designed for less power.
