"A gate turn-off thyristor (GTO) is a special type of thyristor, which is a high-power (.e.g. 1200V AC) semiconductor device. It was invented by General Electric. GTOs, as opposed to normal thyristors, are fully controllable switches which can be turned on and off by their gate lead. See more Normal thyristors (silicon-controlled rectifiers) are not fully controllable switches (a "fully controllable switch" can be turned on and off at will). Thyristors can only be turned on using the gate lead, but cannot be turned … See more The main applications are in variable-speed motor drives, high-power inverters, and traction. GTOs are increasingly being replaced by integrated gate-commutated thyristors (IGCT), which are an evolutionary development of the GTO, and insulated-gate bipolar transistors See more GTO thyristors are available with or without reverse blocking capability. Reverse blocking capability adds to the forward voltage … See more Unlike the insulated gate bipolar transistor (IGBT), the GTO thyristor requires external devices ("snubber circuits") to shape the turn on and turn off … See more " - Gate turn-off thyristor gto
