Capacitance Discharge Ignition System

[jaap de vries]

Dear friends,

I am building a CDI system to ignite fuel mixtures in a pressure chamber for flame speed measurements.
I need a capacitor of about 5 nF, but it should hold up to 10 kV.
Any suggestions on where I can get those. I also need a diode (rectifier) for 10 kV. Also I need high voltage relays.

Ummmm.
Where are you getting you component values from?

Normal CDI, the spark coil generates the HV (10Kv to 30Kv).
With a standard spark coil 100v to 350v on C of 1uf should give about that output range.
So your diodes and relays only have to rated for about 600v.
