Lifter with HV power source

[pavqw]

OK, so I have did some experiments with designing HV power supply.
I have created capacitor multiplier (36x voltage multiplication). It weights cca 8 grams.
It is all SMD technology and works good. My PCB is CNC milled so it is not so great for higher voltages because of shorts - at least for inital tests it is enough.

This multiplier takes input from DC -> AC converter, which is driven by MCU controller, so I can program PWM rates as I need to create required frequencies, etc.
This part is what I have to tune, because I need to find the best transistors (lightweight and yet powerful) at this moment.
Also I have to build/find very lightweight transformer (from 12V to 500-600V).

For now I can get easily lot of KV, but it has to be lowered because of shorts in multiplier.
After this will be tuned, I believe it can power a lifter.

With todays LiPo batteries it could be all very light.

New update..

I have found HiVolt company which manufacturing tiny DC/HV DC converters.

With their devices we should be able to produce 20kV @ 100uA under 20g!
Input voltage is 5V, input current 1A. This is awesome.  With some mods we can obtain even better efficiency.
This could be enough to produce at least propulsion for wing-type craft.

Unfortunately,. their products are quite expensive for me to tests.
I need $1600.

If anyone is interested, you can donate it.
