Marco,
it's not the same! There are lots of types of doubler topologies, half-wave,
full-wave, genuine full-wave and then there are things called "level
shifters".
Your doubler circuit is a level shifter.
I have simulated many kinds of doubler topologies and found IMO the best way
(least parts). It produces quite smooth _steady_ 11kVDC, opposed to the
pulsed dc you achieve with your circuit.
Here's the schematic (4 diodes and 4 caps):

Please let me know if you think there is something wrong with my schematic
or if you know a better way making it.
By the way, how should I protect the diodes from voltage surges from the
primary circuit?
