Abstract
A gate-turn-off thyristor (GTO) that has a fuction of self-commutation is a device that can be turned on like a thyristor with a single pulse of gate current and turned-off by injecting a negative gate current pulse. GTOs have been in existence almost from the beginning of thyristor era, recently are these devices being developed with large power-handling capabilities and improved performance, and they are gaining popularity In conversion equipment. In this paper, the effects of internal parameters of GTO model using a circuit containing two transistors and three resistors the switching operation and the turn-off snubber characteristics is investigated using SPICE program.
