<p>The driving of a GTO (1) to switch on, off and immediately on again due to failed turn-off is controlled by a finite state logic machine (31,32,33,34) which is timed by a digital timing unit formed of a binary counter (35) and programmable decoders (36,37,38,59,40) of the counter configuration which program the time intervals of turn-on, minimum hold duration, and turn-off. <IMAGE></p> |
