As per the subject I am trying to drive a lot of these tubes.
I am the dummy and need a guide !
I have been having fun with just running a few of them and they take about 12mA's per tube fully lit.
Here is a Russian sheet showing various circuit arrangements.
My requirements are that the power supply be current regulated. I also want it to be a universal power supply.
ie: it should run on 110Vac or 240Vac ... switched or automatic.
First my approache was building a flyback style circuit using the ST L6563.
The trouble with that approach is that the output voltage is 400Vdc which means I will have to build a resistive voltage divider to get rid of the extra voltage which will be a waste and will just turn it into a heater.
Try as I might I can see NO way to get the voltage down to 140Vdc using this chip using 240vAC as the input. (kind of obvious really as it is a step UP circuit ! )
Coming at it from another angle was to go all AC and just rectify the voltage at the actual tubes themselves.
This approach is problematic for me as I can see no practical way to regulate the AC coming from the wall socket.
And .. thus onto the tubes.
Someone suggested a ELECTROPHORESIS power supply. So I was looking around for circuits for them.
What I really NEED is half a clue on which way to go with this !
Here is the Russian data sheet.
Please save me from sitting at my computer researching for weeks instead of at my soldering bench building for months !!!
