I don't have a variac and in my country it expensive to buy a one, but I have some high power SCR MCD40-12IO6 mini brick and some high power fast diode DSEI2X101-06A minibrick (I hope they are not fake
) a lot of search I can find again a 2 schematic of "
solid state variac"
http://www.scopeboy.com/tesla/ol2psu.html http://www.scopeboy.com/tesla/drsstc/dr3_variac.gif but it come from 2005 2007 it very old, I have also seen baterry charge based on SCR bridge, not information in google. How could I simulate a variac with an SCR or a way to control that looks like a variac? I would appreciate it if you could give me a schematic. thank
