Do DIACs actually work in Multisim?

Highlighted

Hello,

 

  I've been playing about with Multisim for half a day now, trying to get a simple DIAC/TRIAC AC dimmer circuit working.

 

  I've come to the conclusion that none of the DIAC models seems to functiona s expected - all of them conduct all of the time, regardless of the voltage/current applied to them.

 

  Can anybody point me in the direction of a working DIAC/TRIAC circuit based on the eclectic mix of components multisim has available as standard, please?  I can't find one on the internet despite extensive searching, so I'm starting to wonder if this circuit is actually possible to simulate in multisim...

 

  Thanks.

Now fixed...

 

Guaranteed way to fix anything - get so annoyed about it, you put a posting b*tching about it on a forum...Smiley Frustrated

 

Like a bad workman, though, I'm still going to blame my tools...stupid multisim!

 

Thanks...

Hello,

 

I am trying to do the same thing, but I am stuck, it seems the DIAC does not work properly. Can you please tell me what was your issue ? 🙂

 

Here is what I am trying to simulate, but it seems that the TRIAC/DIAC does not work...
