Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This is a model of a complete inverter drive comprising:

Please note: Be patient, two switching devices cause many event iteratons which cost performance.

Note that due to the voltage drop the voltage at the machine can't reach the full voltage which means torque reduction.

Default machine parameters are adapted to nominal phase voltage 400 V and nominal phase current 25 A.
