Rectifier12pulseFFTExample of FFT block |
|
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This example is based on a 12-pulse rectifier example, calculating the harmonics with the FFT block.
As expected, one can see the 11th, 13th, 23th, 25th, ... harmonic in the result.
