RE: Stiff 24kv DC Power Supply, Filter Caps

Hi Phil,

You got me thinking about this.

On the other hand the large choke will store a fair amount of energy too.
Therefore, the recharge cycle charge will put pretty big demands on the
transformer. It may just come down to experimentation. Additional opinions
welcome.

What about power correction on a three phase transformer. That would be
player in this dance as well, yes?

Long Sparks,
Jim Mora

Jim,

Most of the layouts I've seen have the smaller value cap near the
load, but since you are driving a coil you may want to reverse this
so you can dump more power into the primary each bang.

Hello All,

Having said all that, here's my question: I have a 1mf 40kv bank
(with bleeders) and a 4mf 40kv bank(with bleeders) full bleed time
will be necessarily one minute because of the power involved. The
power supply has a 150H (R=800ohms) Filter Choke on the output.

I can't remember, from way back, which side of the choke gets the
larger value of capacitance. I'm certain that it effects the ripple
cancellation. I do seem to remember that the cap ratio was 8 to one;
but, this is already lethal enough, so 4 is good for me. Can anybody
give me some guidance taking into consideration the gap running
asynchronously (maybe a misnomer in DC) and the primary cap drain at
various BPS'???

As Always, Thanks for your help,
Jim Mora
