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]

Chamberlain's "myQ" technology is embedded in garage door openers and lights, [5] can be added to Wi-Fi networks to control these devices and is being incorporated into future home products, all through a monthly subscription. [6]
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 ...
The $461 GTO package (Code WW3) included a three-speed manual transmission with Hurst floor shifter, heavy-duty suspension with front and rear anti-roll bars, a shaker hood, special grille, wing mirrors, and wheels, and various GTO emblems. The only engine was the 350 cu in (5.7 L) V8 with a 7.6:1 compression ratio and a Rochester 4MC Quadrajet ...
The backbone of any electric gate, whether automatic or not, is the electric gate motor, two distinct motor types exist hydraulic, or electromechanical. This is the electric device which actually enables the electric gate to open and close without having to manually push the gate.
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.
