Re: [CAD_CAM_EDM_DRO] Re: 80V Toroid & Ferrite Beads

A center tapped winding is just one winding with the middle (center) of the
winding brought out to a terminal (tap). Connecting the 2 wires at the ends
of a center tapped winding together is no different than connecting the
ends of a non center tapped winding together and results in a short
circuit. Not what you want. You may be able to get at the center tap on
your transformer and modify it. If the center tap is a loop of wire you can
cut the loop to form 2 separate secondary windings and then connect these
windings in parallel and in phase to get a winding with 1/2 the voltage and
double the current capacity. You may not want to try this at home.
