As Steve already said, the best tuning is the one that produces complete, or almost complete notches in the primary current (and capacitor voltage). At the notches all the energy in the system is in the secondary capacitance. This tuning is achieved, ignoring streamer loading, with a tuning exactly between the two resonances, if the system is designed for this. It is possible to obtain greater secondary voltage, but at the expense of much higher input current, as you probably noticed. If you have a certain maximum input current and a given load capacitance, the system can always be designed to operate in this "notched" way making optimum use of the current and with natural zero current switching. I haveHello, this is my first post, please be kind, I'm working with a team of engineers to build a large solid state musical tesla coil, and my task in to project is to build control and telemetry hardware. We've chosen a full bridge design, a two coil configuration (flat spiral primary), and we're using an interrupter based loosely on steve ward's design to control its switching. Like his, it senses primary current and switches on zero crossing. I've built the hardware and verified that it works in small scale testing...
