Thank you, gentlemen, for your responses re my questions pertaining to = the suitability of a transformer with a 106 Ohm secondary at 5300 volts = and a 120 volt primary. BTW I rechecked the primary

It's worth searching out the Duncan Amps web site and downloading their PSU designer software. It's very informative to get an idea of the peak and rms currents in any situation - rms especially wher

All these questions can be answered by Duncan Munro's excellent PSU Designer software. There's a link from the 'In Practice' page on my web site, where you can also pick up a file containing rectifie

Yea Steve, the issue was with the potential for unequal load sharing between the two windings if they are not nearly identical in terms of impedance. This issue is raised primarily where two transfor

? 106-ohms is decent for some finite load R, depending on the rectification circuit used. - For FWD service, using a C-filter, multiply the secondary R by a constant of c. 300 to arrive at the usuab

That side of it was part of the piece, but I think the writer was also concerned about the possibility of 'backwards' current in the lower voltage winding - I can imagine it being minor where winding
