    I'm new to multisim ... in my course of "Power Electronics" i have to do simulations of SCR (thyristors) on multisim ...

    i want to know how to control the firing angle of SCRs ...

    i think it can be done by connecting Pulse voltage source on GATE of SCR ... but i dont have any idea how to control the firing angle ...

    for example : how to set firing angle to 30 degrees or 60 degrees .

    and my other question is that how to set overlap angles when two devices are working at a time ..
