I have a TDK CXA-2090 CCFT Inverter board that I want to use as a DC -> DC voltage step-up, from 3 volts to around 150 volts, to charge a capacitor with. I couldn't find schematics, but the inputs and outputs are similar to the CXA-L10A, but without the number 4 pin. I've been able to successfully power a neon lamp, with the inverter providing 120V AC.
However, I'm very perplexed by the behavior of the output pins. They defy all the laws of electronics that I know (which probably means I need to learn more electronics!). Basically, a neon lamp will glow if only one lead is connected to the high output, with the other dangling free. Also, (and I can't explain this any way other than exactly how it happened) if I connect a wire, in this case with alligator clips one each end and 17.5" long including clips, then the low output will power the lamp as well. I don't necessarily need to know why this happens, but if you feel the need to enlighten me, please do. Really all I need is a way to charge a capacitor with this circuit, that will not overvolt the capacitor.
