2-Level MOSFET Converter
Purpose
Three-phase two-level MOSFET converter.
Library
Converters
Description
Implements a three-phase two-level MOSFET converter with reverse diodes. The
gate input is a vector of three signals - one per leg. The upper MOSFET, connected
to the positive dc level, is on if the corresponding gate signal is positive. The lower
MOSFET is on if the gate signal is negative. If the gate signal is zero both
MOSFETs in the leg are switched off.
You can choose between two different converter models:
- The basic 2-Level MOSFET Converter is modeled using the
component MOSFET with Diode. PLECS needs only six internal switches
to simulate this converter. Only the on-resistances of the MOSFETs can
be entered.
- The Detailed 2-Level MOSFET Converter is based on individual
MOSFET and Diode components. In this model you may specify forward
voltages and on-resistances separately for the MOSFETs and diodes.
