GTO

Purpose

Ideal GTO with or without forward voltage and on-resistance.

Switches

Description

[Picture]

The Gate Turn Off Thyristor can also be switched off via the gate. Like a normal thyristor it closes if the voltage between anode and cathode is positive and a positive gate signal is applied. It opens if the current becomes zero or if the gate signal becomes negative.

Parameters and Dialog Box

[Picture]

Width
The width of the component. This affects both the width of the electrical ports and the width of the gate input signal. The default is 1.

Each of the following parameters may either be a scalar or a vector with the width of the component:

Forward voltage
Additional dc voltage V f in volts (V) between anode and cathode when the GTO is conducting. The default is 0.
On-resistance
The resistance Ron of the conducting device, in ohms (_O_). The default is 0.
Initial conductivity
Initial conduction state of the GTO. The GTO is initially blocking if the parameter evaluates to zero, otherwise it is conducting.

Probe Signals

GTO voltage
The voltage measured between anode and cathode.
GTO current
The current through the GTO flowing from anode to cathode.
GTO conductivity
Conduction state of the internal switch. The signal outputs 0 when the GTO is blocking, and 1 when it is conducting.
