Thanks to all who responded to this thread. Though this scheme does work, it
doesn't produce the same results. I didn't do the math the first time
around.
My two xfmrs are 1100 VAC. If I series the secondaries and feed a FWD
circuit, I'd get:
1100 VAC + 1100 VAC * 2.8 = 6160VAC
If I feed each individual xfmr to it's own FWB then series the results I
get:
(1100 VAC * 1.4) + (1100 VAC * 1.4) = 1540 VAC + 1540 VAC = 3080 VAC
It could see the circuit in my head but I didn't do the math. If I want the
6kV or so from the supply I need to series the secondaries and run a FWD and
live with a 60Hz charging rate.
Thanks to Jim VE7RF for showing me my error.
