EMCO makes inexpensive low power HVDC power supplies.

Google EMCO high voltage and look at their 'F' series. They are adjustable HV supplies, 10 watts, at up to 12kV out. Their output voltage is variable with their input voltage (like you can get a 0-5kV unit that does 2ma out, or a 0-10kV output @ 1ma).

They are about $150 apiece but you don't have to futz around with ignition coils or flybacks if you only need a little current. Nice and small too, PCB mount.

Don't try to rectify and filter HV AC. I've been there. It sucks.

Also, if cost is no object, look at Ultravolt high voltage power supplies. 24VDC in, and they have models that will do 30 or 40kV out, very nicely regulated. They are expensive at over $700 for most models (the ones I've used anyway (C30)).

These are what we use at work FWIW.

well i dont see why pulsed hvdc wouldn't work.i mean it would work surely because alot of lifters use just voltage multiplication units to power them and the dont have full-bridge rectification,so it is basically ac...it pulses 30 time/second so it is still ac.and the higher the frequency the higher the negative ions

i dont even know alot about lifters but there you go....hope it works for you.(if you use an ignition coil you'd need a multiplier for a big lifter though)
