Description

[Picture]

Implements a three-phase two-level IGBT converter with reverse diodes. The gate input is a vector of three signals - one per leg. The upper IGBT, connected to the positive dc level, is on if the corresponding gate signal is positive. The lower IGBT is on if the gate signal is negative. If the gate signal is zero both IGBTs in the leg are switched off.

You can choose between two different converter models:

The electrical circuit for the converter is shown below:

IGBT forward voltage
Additional dc voltage V f in volts (V) between collector and emitter when an IGBT is conducting. The default is 0.
IGBT on-resistance
The resistance Ron of a conducting IGBT, in ohms (_O_). The default is 0.
Diode forward voltage
Additional dc voltage V f in volts (V) between anode and cathode when a diode is conducting. The default is 0.
Diode on-resistance
The resistance Ron of a conducting diode, in ohms (_O_). The default is 0.
