2-Level IGBT Converter
Purpose
Three-phase two-level IGBT converter.
Library
Converters
Description
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 basic 2-Level IGBT Converter is modeled using the component
IGBT with Diode. PLECS needs only six internal switches to simulate
this converter. No parameters can be entered.
- The Detailed 2-Level IGBT Converter is based on individual IGBT
and Diode components. In this model you may specify forward voltages
and on-resistances separately for the IGBTs and diodes.
The electrical circuit for the converter is shown below:
