Abstract :
A model is presented of the gate-turn-off thyristor (GTO), which can be matched to measured data and incorporated in the SPICE computer-aided-analysis program. The model consists of a circuit containing two transistors and three resistors, which is the circuit configuration need to simulate the S-type negative-differential-resistance (NDR) I-V characteristics of the GTO. The authors give a method for selecting the resistors and transistor parameter in order to achieve a specified forward breakover voltage, holding current, and turn-off gain. Examples of the SPICE-generated static and dynamic performance are given
