FYI -- For me, it still hangs (or takes a VERY long time) when I include the REPEAT FOREVER ... ENDREPEAT around the PWL file.? I do not have experience with that particular format, so I can't tell

Thanks, indeed, that's the point. I have to do an iteration step in my script. -- Christoph

Anirban asked about finding Triac models. There are several Triac models already in the group's Files.? Finding them might be a challenge, because it's best to search for a part number, rather than

Excuses. I forgot to disable my message signing when posting the corresponding message. ANd the term from LTSPICE's view is PWL; of course. But I'm thinking in "PWM" at the moment since the data form

Can any one help me with adding a Triac model in my schematic? I am trying to simulate with ST?AC Switch but couldn't find a spice model for such. Any idea where can I? I am also open with LittleFuse

Christoph uploaded another file (PWM_less_pulses.zip) but forgot to send a message about it.? The description with Christoph's newer file is: "Still don't find the culprit. It fails on last line.

That's how multilevel converters allow for lower switching losses & EMI to divide down V steps to suppress EMI. Sign waves allow higher PF, but if not AC 60 hz line based then not as helpful. Since a

Christoph, Try it without the REPEAT ... FOREVER.? You have problems in the .txt file.? Time points are not in order.? I suggest fixing that first, then adding on the REPEAT part. Andy

Richard wrote, " Aren't IGBT's supported on version 4.23I? " Yes and no.? Actually, the answer is yes, but with a twist.??This has no effect on the present discussion, but it might affect you if

I tell a lie. An intrinsic model for IGBTs was introduced some time since LTspiceXVII was introduced. From the Help: Old member analogspiceman did a lot of work on IGBTs including with the new

Actually, point 3 is not removed. Duplicates do cause problems. If I were you, I would also stick to one time range multiplier. Mixing milliseconds and nanoseconds is asking for trouble. And that's

I had this once but thought I had sorted that out. Gotta review the value genration alogorithm again. -- Christoph

I get an error message saying that the PWL values in the text file are not in chronological (time) order.

Actually the file has 256 rows (the signal interval is divided into 256 bins), but even with these 8 values, LTSPICE hangs. -- Christoph
