Fourier Source
SIMPLORER 6.0 — Manual 99
>>Basics>Circuit>Sources
The component represents a Fourier source. The EMF value of the Fourier voltage source results
from the ripple amplitude of the defined sine waves. The values can be imported from a
.mdx file created in the DAY Post Processor through an FFT analysis. In addition, you can also
define the fundamental harmonics and the number of sub harmonics in the component dialog.
Within the dialog you can choose a voltage or current source.
The component cannot be used with AC and DC simulation.
Dialog Settings
� «Source Type»
In the list, select Voltage or Current Source.
� «Harmonics»
Select All, Even or Odd harmonics. The setting is active in the table on the right hand side.
When you the define the «Number» of harmonics all or only the even or odd harmonics are
considered.
� � «Phase»
If the box is deactivated, you can define your own values in the corresponding text box on the
right hand side. Click in the list field and enter the phase value either in degrees or in radians.
«Ampl.»«Ampl. [%]»
Click the corresponding field in the list and type the value of the amplitude either as absolute
or proportional value. Please note, you cannot define a variable or an expression in this case.
Only a number is accepted.
«Fundamental Frequency»
Defines the fundamental frequency. This value is the basis of all harmonics listed in the table.
«Number»
Defines the number of harmonics considered in the simulation. Please note, you cannot define
a variable or an expression in this case. Only a number is accepted.
� � «File Name»
If the box is checked, you can define a .mdx file with the corresponding data. See also 14.2
“SIMPLORER ASCII System Data Formats” on page 467.
