A gate turn-off thyristor (GTO) is a special type of thyristor, which is a high-power (e.g. 1200 V AC) semiconductor device. It was invented by General Electric . [ 1 ] GTOs, as opposed to normal thyristors, are fully controllable switches which can be turned on and off by their gate lead.
An ETO is turned ON by applying positive voltages to gates, gate 1, and gate 2. When a positive voltage is applied to gate 2, it turns on the MOSFET that is connected in series with the cathode terminal of the PNPN thyristor structure. The positive voltage applied to gate 1 turns off the MOSFET connected to the gate terminal of the thyristor. [1]
A thyristor (/ θ aɪ ˈ r ɪ s t ər /, from a combination of Greek language θύρα, meaning "door" or "valve", and transistor [1]) is a solid-state semiconductor device which can be thought of as being a highly robust and switchable diode, allowing the passage of current in one direction but not the other, often under control of a gate electrode, that is used in high power applications ...
The wafer device is similar to a gate turn-off thyristor (GTO). They can be turned on and off by a gate signal, and withstand higher rates of voltage rise (dv/dt), such that no snubber is required for most applications. The structure of an IGCT is very similar to a GTO thyristor. In an IGCT, the gate turn-off current is greater than the anode ...

Aluminium gates, being lightweight, work well with brushless motor operators, as the motors do not have to work as hard to maneuver the gates. This not only enhances the overall performance and reliability of the gate system but also contributes to energy efficiency, leading to cost savings in the long run.

The electric overhead garage door opener was invented by C.G. Johnson in 1926 in Hartford City, Indiana. [1] Electric Garage Door openers did not become popular until Era Meter Company of Chicago offered one after World War II where the overhead garage door could be opened via a key pad located on a post at the end of the driveway or a switch inside the garage.
