Information

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

Transforms dq currents or voltages to three-phase currents or voltages.

The desired d- and q-components of the space phasor in rotor fixed coordinate system are given by inputs d and q. Using the given rotor position (input phi), the correct three-phase values (output y[3]) are calculated. They can be used to feed a current source which in turn feeds an induction machine.

Inputs d and q can be given either as peak values (useRMS=false) or as RMS (useRMS=true). The correction by factor √2 is done automatically.
