The proper method of turning a GTO is by applying a positive gate current when forward voltage is applied. Application of positive current at the gate injects holes into the P gate region which makes j3 forward bias. Thus allowing the current flow through it.
Due to the superior switching characteristics and turn-off capabilities with no need for a commutation circuit, GTO is preferred over conventional thyristor in various applications. Some of these applications of GTO are given below: It is used in high-performance AC as well as DC motor drives.
Some of these applications of GTO are given below: It is used in high-performance AC as well as DC motor drives. It is used in VFD (Variable Frequency Drive) with adjustable frequency. It is used in DC-to AC or DC-to-DC converters. It is used in DC choppers. It is used in inverters.
GTO (aka Gate Turn Off) is a semiconductor based fully controlled unidirectional switching device (thyristor) that has 3 terminals Gate, Cathode, and Anode. It can be switched ON/OFF using the gate terminal. A positive current pulse at the gate switches ON the GTO while a negative current pulse at the gate switches it OFF.
The GTO operates like a conventional thyristor except it has turn-off capabilities. GTO has the same turn-off operation as a conventional thyristor. It can be turned-on using two methods i.e. increasing forward voltage above break over voltage, applying positive gate current.
