Three-phase three-level neutral-point clamped IGBT converter.
Converters
Implements a three-phase three-level IGBT converter with neutral point
clamping. The gate input is a vector of three signals - one per leg. The topmost
IGBT, connected to the positive dc level, is turned on if the corresponding gate
signal is , and the second IGBT if the signal is
. The third IGBT is turned
on for signals
and the lowest one for signals
. Gate signal values of
,
and
connect the phase output to the positive, neutral and negative dc level.
By applying a non-zero signal at the inhibit input marked with "x" you can turn off
all IGBTs.
You can choose between two different converter models:
The electrical circuit for the converter is shown below:
The three-level IGBT converters provide 36 probe signals grouped by leg. Each signal is a vector containing the appropriate quantities of the individual devices: voltage, current, conductivity, conduction loss and switching loss. The vector elements are ordered top-to-bottom.
For the Detailed 3-Level IGBT Converter the diode probe signal vectors are in the order: anti-parallel diodes (top-to-bottom), clamping diodes (top-to-bottom).
