Description

[Picture]

The Insulated Gate Bipolar Transistor is a semiconductor switch that is controlled via the external gate. It conducts a current from collector to emitter only if the gate signal is not zero.

Parameters and Dialog Box

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 collector and emitter when the IGBT 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 IGBT. The IGBT is initially blocking if the parameter evaluates to zero, otherwise it is conducting.

Probe Signals

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