Hello,
I'm trying to have a working TRIAC model on LTSpice.
From www.teccor.com I got the following model that I saved to
a
file called triac.sub. I've put this file on lib\sub folder. On the
squematic I've put the ".INCLUDE triac.sub" Spice directive.
Hello Brusque,
you were faster with your second posting as I could answer your first
one. I wanted to recommend the teccor company too.
But everytime I try to start the simulation I got the message:
SPICE Error
Too many parameters for subcircuit type "q8025r5"(instance:
xu1)
On the "Component Attribute Editor" I have:
Prefix X
InstName U1
SpiceModel triac
Value Q8025R5
Value2 <none>
SpiceLine <none>
SliceLine2 <none>
Please, I need help.
The field SpiceModel must be empty. That's the only mistake.
You only add the TRIAC symbol from the "misc" directory. Then "right
click" the mouse over the word TRIAC and change it to Q8025R5.
Shure, the command line with the models must be added to the
schematic. Example: .INCLUDE tectriac.lib . Put this file into the
lib\sub directory of SwitcherCADIII.
Have you read the datasheet of this high power TRIAC? It needs nearly
100mA gate current to switch on. Just a hint for the circuit in your
simulation.
Have fun with LTSPICE.
