[Amps] Voltage Doubler Regulation

[Mike]

Richard, take a look at this web page figure 2. It takes more diode strings
but gives very good
performance over what the standard handbook FWD circuits we've been
accustomed too! Use 6a10 diodes
from mouser...cheap... http://208.190.133.201/lit/4x8/index.html

Take note C4 is critical for best regulation and it only takes ~10-20ufd. An
oil filled cap
or one of the russian poly hv caps listed on ebay works fb.

The lower the sec R of the high V transformer the better, very important! A
boat anchor tranny with 50 ohm
Secondary will not work well ;-))

Hope this helps!

Mike, K4EAR

Subject: [Amps] Voltage Doubler Regulation

I would like to look at ways to improve the Voltage Regulation in a Voltage
Doubler Circuit.
I tried Google, but didn't get much on the actual calculations involved.

Since we have certain givens; such as The AC Line is what it is, the Plate
Xfmr is what it is, the only variable in the equation would be the Capacitor
value. Am I correct in that assumption ?

Can anyone point me to a reference that I can use ?

Thanks, Dick, W1KSZ
