What are you trying to do? Are you just making a high voltage spark? Does it need to be synchronized with anything?

Do you mean 8kV?

Your link does not work.

8kw is an awful lot for an ignition coil. I think he means 8kv.

I recommend this one from RMCybernetics: https://www.rmcybernetics.com/projects/DIY_Devices/homemade_pulse_controller.htm

Frequency and duty cycle are adjusted independently of one another. The main thing you really need to be sure of is that your power source is able to produce enough current to drive the coil, which is usually >5 amps.
