WebbA gate turn-off thyristor (GTO) is a special type of thyristor, which is a high-power (.e.g. 1200V AC) ... It may be noted, however, that the turn-off time of a GTO is approximately ten times faster than that of a comparable SCR. To assist with the turn-off process, GTO thyristors are usually constructed from a large number ...
