I am looking for an off-the-shelf transformer that will step up a
12Vpp 70KHz square wave to around 10-20KVAC.It is for an electrostatic experiment, so very little output current is needed.
I have tried ignition transformers, auto coils, audio coupling, and TV flybacks, but none were efficient at that high frequency.
I can not afford to have one custom wound.
Does anyone have any suggestions? I am happy to put a few in series if that is what it takes.
I am thinking maybe a tranny from an inverter or SMPS, but not sure exactly where to look.
Thanks,
Kevin Foster
