Sorry everybody about the "flywheel" capacitor effect. I guess I have used
a wrong terminology :(.

With flywheel capacitor I just meant a capacitor sensibly bigger than the
primary capacitor, so that when connected in parallel with it would loose a
relatively small amount of charge.

For instance, if you charge a 10 uF capacitor with 10 kV and then connect
in parallel a 0.1uF, the resulting voltage between the two's terminals will
drop only to 10 kV - 1% = 9.9 kV.

The bigger cap works as a "flywheel" in that it keeps the original power
supply peak voltage "up" (VAC * 1.41) even when the power supply rectifier
bridge is not conducting.
