Kurt,
There is full info on modelling voltage doublers on the Duncan amps =
site.
You do not have to download and store, you can simply open the site and =
do the exercise.
cheers
Baz

Subject: [AMPS] Additional Info Voltage Doubler/Filter Capacitance
Hello All:
Thanks for the info so far. Additional info is as follows: The =
transformer was designed to be used with a doubling rectifier. The =
secondary is 900 volts +or- 5%. The secondary resistance is 16 Ohms. =
(primary will be wired for 240V).
I suppose I would use a full wave voltage doubler. Unfortunately I =
don't have the publication containing the Orr Chart. If some one has it =
and would like to plug in the info I provided, that would be a =
tremendous help.
I also checked the Duncanamp website, looks very interesting. I =
checked the index and didn't see anything helpful with a doubling =
circuit, however I didn't venture too far, my system is windows ME and =
it didn't look compatible, I'm a bit of a chicken when it comes down to =
loading incompatible programs, this comes from the pain and scars =
delivered by the boss when I ask her to straighten out the computer.
Anyway I hope the additional info I provided will help with how much =
capacitance you think I will need in each leg of the rectifier. Thanks =
again, Kurt...
