Hi Folks!
I was just curious as to why the center tap of the mains transformer secondaries are tied to the junction of the power supply's (totem pole config'd) first stage filter capacitors? Does this effectively create a voltage doubler arrangement? With the FWB rectification scheme, I would think that one could float the C.T. entirely. TIA!
Oh, here's some schematics that illustrate what I am talking about, they are all pdf's. The Orange schematics are the more simple ones (2nd & 3rd):
