[TCML] Help with custom capacitor design

Hi All,

I’m working on a large 3-phase DC resonant charged magnifier coil and would like to attempt to order a custom capacitor to enable a small, neat and compact design.

The coil is going to run at about 15kVA with the primary cap charged to near 18kV at 500BPS. I expect Fres to be between 75 and 100kHz, so peak primary currents of perhaps 2000 to 3000 amps. 

I was thinking I would specify a 40kV DC and 5000 amp peak rating – how does that sound? 

Now, is anyone able to offer some advice regarding the specs I should request for things like:

RMS current,
DV/DT
ESL
ESR
Ripple Voltage (assume 100%???)
Etc

Any advice would be greatly appreciated!

Regards,

Greg
