A gate turn-off thyristor (GTO) is a special type of thyristor, which is a high-power (.e.g. 1200V AC) ... The typical application for symmetrical GTO thyristors is in current source inverter. GTO thyristors incapable of blocking reverse voltage are known as asymmetrical GTO thyristors, abbreviated A-GTO, and are … See more 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 … 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 … 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 GTO thyristors are available with or without reverse blocking capability. Reverse blocking capability adds to the forward voltage drop because of the need to have a long, low … 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 WebMOS Turn-Off Thyristor (MTO) MTO stands for MOS turn-off thyristor. It is a high-power bipolar MOS thyristor that constitutes both MOSFET and Gate Turn-off thyristor (GTO). It was developed as a replacement for GTO. It is a latching device that outperforms MCT and IGBT when it comes to power and blocking voltages.
