If you need about 12,000 volts DC for an ion generator this circuit might be the ticket. It draws power from the 120vac power line but it uses a
small 6KV camera flash trigger coil. The output signal is isolated from the power line. Although the circuit can only deliver about 5uA of current it can produce dangerous shocks, so be careful.
Nitrogen or air sparks are very powerful light sources that produce flashes that last only a fewnanoseconds. This line
powered circuit generates a continuous series of very small sparks acrosselectrodes with a 0.05 inch gap.

Ignition Coil/Flyback Transformer Based High Voltage Generators: This page gives my thoughts on how to use a car ignition
coil or Flyback transformer as a high voltage generator. The objective is to produce as high a voltage as possible, with as high a power throughput as possible. (added 4/02)
Virtual zener circuit simplifies high Voltage interface: 03/20/03 EDN Design Ideas / (added 1/05) This design
for a photonic switch needs more than approximately 70V at the cathode of a duo-lateral optical position-sensing device. This voltage gets speedy response at longer wavelengths, such as 980
nm. The circuit uses fast transimpedance amps, "floated" at 70V. Two "virtual-zener" circuits step down the high-voltage signals for subsequent processing in a ground-referred differential-amplif......
