How much gate current do I need to turn off a GTO?
The gate current required to turn off the GTO is relatively high. For example, a GTO rated with 4000V and 3000A may need -750A gate current to switch it off. So the typical turn off gain of GTO is low and is in the range of 4 to 5. Due to this large negative current, GTOs are used in low power applications.
Can a GTO be turned off without reversing anode voltage?
The GTO can be turned OFF by the application of reverse gate current which can be either step or ramp drive. The GTO can be turned OFF without reversing anode voltage. The dashed line in the figure shows i-v trajectory during the turn OFF for an inductive load.
When does GTO start conducting in reverse direction?
It is observed that, during reverse biased condition, after a small reverse voltage (20 to 30 V) GTO starts conducting in reverse direction due to the anode short structure. This mode of operation does not destroy the device provided that the gate is negatively biased and the time of this operation should be small.
How is the turn on operation of GTO similar to thyristor?
Principle of Operation. The turn ON operation of GTO is similar to a conventional thyristor. When the anode terminal is made positive with respect to cathode by applying a positive gate current, the hole current injection from gate forward bias the cathode p-base junction.
When did the Pontiac GTO become a separate model?
The Pontiac GTO is an automobile that was manufactured by American automobile manufacturer Pontiac from 1964 to 1974 model years, and by GM’s subsidiary Holden in Australia from 2004 to 2006 model years. The GTO became a separate model from 1966 to 1971 (VIN 242…).
Can you buy a Pontiac GTO on eBay?
Purchasing a GTO on eBay has the potential to save you the time of searching for a car in your area or by looking through classified. However, there are a few other criteria to run through that may help you choose the car for you: Transmission. Most listing will clarify whether the listed car is a manual or automatic transmission.
When is the best time to buy a Pontiac GTO?
If you are looking for a running classic car or a project car to restore, then a 1960s or 1970s model may be the right choice for you. However, if you are looking for a late-model GTO, there are plenty of ready-to-drive 2000s models to choose from. Particularly if you are looking for an older model, you may run into project cars.
What kind of transmission does a 1965 Pontiac GTO have?
Car Life tested a 1965 GTO with Tri-Power and what they considered the most desirable options (close-ratio four-speed manual transmission, power steering, metallic brakes, rally wheels, 4.11 limited-slip differential, and “Rally” gauge cluster)]
