How to design a firing circuit to control power electronic devices using multisim?

 

You can use 'pulse voltage' to design it.

You can use 'pulse voltage' in voltage section.

or this old thread if you want to design in pspice.............................http://forum.allaboutcircuits.com/threads/thyristor-firing-angle-in-multisim-or-pspice.28189/

 

Thanks.
