ABSTRACT:
A device for triggering a thyristor uses light pulses or flashes for achieving a galvanic separation between the triggering circuitry and the load circuit. The light pulses are generated by a flashlamp disposed in a housing in which a number of channels extend radially, each channel having a light conductor therein. The light conductors lead to respective individual thyristors which are to be triggered.
