Inverter – Parameters, Inputs and Outputs

This section provides the description of all parameters, inputs and outputs of the
"Inverter" part of the model.

Properties of the Inverter Model

The inverter model has the following properties:

• Switches can be high- or low-active

• Simulation of hardware failures (switches always open or closed)

• Simulation of phase voltages U_Phase_X (X = U, V, W) and U_d, U_q

• Simulation of phase voltages on free wheeling (all six inverter switches

open)

• Simulation of DC voltage link

• Simulation of voltages across a switch and of current through the switch

• Simulation of ohmic losses in switches and diodes.

• Information on phase errors (upper and lower switches are open simulta-

neously)
