Ballast question

I'm a newbie on ballasts

However I'd like to play around with the voltage waveform after a tube lits up.

For example providing a triangle wave (instead of sine) voltage to the tube at various amplitudes etc.

So, how does a typical voltage waveform look across a typical tube? And how does a current waveform look for current flowing into a typical tube?

And next, how can I make / integrate a ballast that will shoot the waveform immediately after the tube lits up?

Any hints/ advise / discussion / pointers would be greatly appreciated.

Regards, Mike

The voltage waveform will spike up to the ignition voltage of the plasma, and then plummet to practically zero when the plasma starts to conduct.

Plasma has a negative resistance - when the current flow increases, the voltage drop decreases.

I am kind of wondering what it is you intend to accomplish here.

Good Luck! RIch
