Simulation of AC Voltage Control circuit using DIAC-TRIAC in LTspice

[@ahmettevfikcakir2303]

Thank you for this great video. How can I add filter to this schematic?

Amazing lecture... very informative...!! nice tricks...!!

Thanks

The LTspice error flagged on line 22 , 1.462* 0.342, is the value of resistor R_R1 in the DIAC model library.
The line reads "R_R1 N02098 TRG 1.462*{Tr}". The proper syntax for the value of R_R1 should be R=1.462*{Tr}.
LTspice cannot interpret the resistor value and ignores the error, resulting in an incorrect value for R_R1.
PSpice interprets this improper syntax correctly in spite of it violating its own syntax rules.
The solution is to edit the model file and add the "R=" to the statement.

Thanks you very much, very clear explanation.

[@InderjitSingh87]

Glad it was helpful!

[@dariushgc]

thank you bro. you explain very well

[@InderjitSingh87]

Glad it helped

Hi Inderjit, is it possible to trigger OFF the TRIAC at pi/4 and turn it ON at pi/2 with the schematic diagram you have shown here?

[@elcindotech]

I did the same simulation with you, but the results are not the same as the simulation you played. negative waves are not present in the DIAC output, do you want to provide a solution? Thank you

how to get spice componnets libraries

[@kekecjan]

Would be really nice of you to share diac and traic subcircuit, because there's no such files on STMicroelectronics.

[@kekecjan]

sorry, nvm i found them... still would be easier to just share them. thanks

[@InderjitSingh87]

Its shown in video how to integrate them in LTspice.

[@kekecjan]

@@InderjitSingh87 yes but i ment tiac and diac files for simulation. Its easier to just save them on the cloud then share them via link. thanks for replay !

[@nieli1798]

Thank you

[@poojapoonia6220]

Which simulation tool you used in it ?

[@InderjitSingh87]

Its LT Spice
