Extreme High Voltage: ZVS Flyback Driver, 28 V Input, Effect of Capacitance on Spark

I show the effect of added capacitance on the psarks (arcing sparks, tm TKLabs) emitted by the Flyback driven by the ZVS Royer oscillator. I have about a hundred of those 400 pF, 30kV high-quality BaTiO doorknob caps. It’s not often I find an appropriate use for them. Compared are no added capacitance, 200 and 400 pF added.
