Controlled (Thyristor) Three-Phase Full-Wave Rectifiers in LTspice

[Maverickans]

Hello, I'm trying to simulate a 3-phase, 6-pulse Thyristor Bridge Rectifier on LTspice, but I can't seem to get the results. Here is what I have so far. Could someone please guide me on this? Thank you!

Could you please attach a copy of your schematic filename.asc to a post. Do it by adding an extra extension, to make a text file called filename.asc.txt

You can do the same with the plot filename.plt extending it to filename.plt.txt

Then we can remove the .txt extensions, and run your simulation without the problems of poor picture quality.

Hi Baluncore, thanks for your reply. Please find the files attached.

The SCR you are using is not in my old LTspice library.
What model of SCR are you using ?
Where did you get the files for that SCR ?

Oh, my bad. I found it (Thyr_All.asy) from here: https://ltwiki.org/files/LTspiceIV/lib/sym/Robertugo/
