Has anyone build a "motor-less" model yet? That is, one without the conventional turbines or motors, using some kind of solid-state drive system?
I'm still trying to get my system to work, its based on the JLN Lifter design but using some novel driver circuitry to get the required 50+ watts (28KV+ at 2mA)
Have come up with a few ideas but the main problem I am having is with the multiplier stage which keeps burning out. Its not overload, I've put a 1M resistor on the output and it worked for a while then failed again. It doesen't make sense, almost looks like the diodes are randomly failing.
I'm using a cold cathode fluorescent tube (CCFL) driver which I have modified to get the required 1600V p-p to drive the multiplier.
Any ideas? I was thinking along the lines of a "MARX Generator" using high voltage thyristors as the switching elements.
