I am looking for a reliable way to multiply the voltage from a standard wall outlet to power a DRSSTC at 240v or even possibly 480VAC down the road. I have some (x4) F1892RD1200'S and I was told that I can use these to make a multiplier but for a DRSSTC would it be reliable enough? I am trying to avoid purchasing a 120-240v transformer or 0-240v variac. I already have a 0-140v variac that I have been using up until now.

I dont see why not, Ive seen and done +2kW simple multipliers, its just the component values, quality, and cost, oh and the inital power up surge and PF. Since they have poor PF you should consider PFC if you need it.

I wanted reasonable smoothing, so I just used two 1900uf caps @ 450vdc each. I had reasonable results with 1000uf caps. It has worked quite well. Is it efficient? I got somewhere near 85%-90% with some crude measurements.
