I was just wondering(as always whats wrong with using a voltage doubler
recifier circuit? (i.e., where you use 2 diodes from the tranformer to
double the voltage)
like I have a 25VCT transformer and it would be nice if I could double that
and use a variable regulator to get me a larger range but I feel that there
is something about the doublers and so on that I don't know about... The
only "hint" I have read is that they are mainly used to supply pulses such
as in photo flashes and such... (hence implying that they shouldn't be used
continuously?)
Obviously it changes the ratings of things up and stuff(have to use larger
filter caps and worry about increased power dissipation and things like
that)?
My gut feeling is that the ripple is probably doubled too(hence for, say, a
quadrupler it would take time to recharge the caps hence a big dip).
Just for fun, could I use like a 20x to get the voltage real high if I had
the diodes and caps that could handle those voltages to, say, make a big
spark?
Thanks,
Jon
