Information

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

This example is based on a 6-pulse rectifier example, calculating the harmonics with the FFT block.

As expected, one can see the 5th, 7th, 11th, 13th, 17th, 19th, 23th, 25th, ... harmonic in the result.
