- C: This graph is behaving as the one before (B), but it draws the waveform showing how
the harmonics will look like when the user uses an oscilloscope in the output (EUT side).
- D: Theoretical values are very useful to know which is the maximum output voltage, as
well as the peak, the crest factor and the total harmonic distortion (THD).
- E: Open, save or send .csv files with the following buttons
o Open Folder. Open a folder of the computer with .csv files in it. The files will be
shown in window F.
o Save File (.csv). This button allows to save a created harmonic in A window or to
modify an existing opened file.
o Send File. The created file in A or the opened and selected file in F will be sent
by pressing this button. To sum, the sent file will be the one shown in A, B, C
and D.
o Send Sequence. The user can send a sequence instead of a unique file. The file
sequence to execute will be the one with the harmonic files in F window that
the user has opened.
o Repeat Sequence. By pressing this button, the LED right beside it will be
illuminated and it will indicate that the sequence is going to start again when it
is finished.
o Time. It shows the time in seconds that the actual file will last until it goes to the
next file.
o STOP. The user can stop the sequence any time, but the equipment will stay in
the actual file. This button is not a button to stop the converter but the
sequence.
- F: This window will show the name and the location of the file that the user opens from
the button Open Folder of part E. it is possible to select (double click) one file and the
characteristics of it will be shown in windows A, B, C and D. To create the order of the
sequence, click the file and move it up or down with the buttons Move Item Up and
Move Item Down.
When the user creates a .csv file with excel or a text editor, it is important to write
in the first column, as in the example above, the number of the fundamental and
harmonic (from 1 to 15) and the words Desf and Time [s]
Each file is a state so, to create a sequence, different files must be created and saved in the same
folder. From the interface, the user can visualize all the files of this folder, send each file into the
converter or perform the sequence.
The same example of csv file explained above with excel is shown in the following
image with a text editor. Please note that the columns are separated with comas
and the decimal points are points.
