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]
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.
In comparison to the NS 6400 and DE 1002, the Di 8s are 3.0 meters (9.8 ft) (NS) and 4.4 meters (14 ft) longer. The electrical transmission system saw ABB systems replaced by Siemens and the installation of GTO and IGBT systems. The power output was significantly improved, from between 1,120 and 1,380 kilowatts (1,500 and 1,850 hp).

Gate turn-off thyristors (GTO) were used to control power to the traction motors, hence allowing for smoother acceleration. [3] Following the successful implementation of chopper control, these features were installed on the Tangara and later V set carriages .
The Pontiac GTO is a front-engine, rear-drive, two-door and four-passenger automobile manufactured and marketed by the Pontiac division of General Motors over four generations from 1963 until 1974 in the United States — with a fifth generation made by GM's Australian subsidiary, Holden, for the 2004 through 2006 model years.
Remote controls send a digital code word to the receiver. If the receiver determines the codeword is acceptable, then the receiver will actuate the relay, unlock the door, or open the barrier. Simple remote control systems use a fixed code word; the code word that opens the gate today will also open the gate tomorrow.
