LTSpice Thyristor\SCR Library?
« on: August 26, 2014, 09:29:26 am »
I am just trying to track down a library to use in LTSpice that has some basic thyristors\SCR's. I found this: http://www.littelfuse.com/technical-resources/spice-models/thyristor-spice-models.aspx and a few others but I can't get them to load in LTSpice (I tried adding the library and changing the blank SCR model to reference the library item but kept getting errors).

I was wondering whether someone could confirm whether these work for them and how they did it, or whether these don't work, or if someone has a good library of SCR\Thyristors I can use?

Thanks.

Works for me
I did following: download library file
add spice directive .lib <path to library file> to your simulation schematic
add SCR symbol from ltspice symbol library right click it and replace the SCR with correct thyrsitor model eg: EC103D1 and then thing should work

attached thyristor library and simulation example

Okay that's really strange... It will only let me add the library if I save my project into the lib folder, even if I add the directory of the lib into the project using the browse button. Oh well it seems to be working, thanks a lot for taking the time to test that for me!
