Sharing current through diodes

[rtarbell]

Normally, one can not parallel diodes to share power because one diode will turn on before the others, and this diode will then hog the current from the others.

==> What about using MOS diodes (taking a power FET and tying its drain to gate) in parallel? Will they share the current more equally?

series R works, costs a little extra V drop

for ps rectifiers you could use multi-filar sec winding so R and V match between wires and parallel the outputs of the diodes on each of the sec wires
