what are the odds that this would by a very loooonng shot work?
« on: October 06, 2014, 12:03:46 pm »
its a ... trashy mod of a camera flash auto-trans ... and i might have a 3:3:7000 transformer coming (though circuit is 12500) ...

Vin 6v, Vout (simulated no load) 24kV  (Q drive 1.26v) :-DD (i must be kidding myself)
RGP02-20E = 2kV reverse V each

Just a little critique; this diagram would be a lot easier to follow if you used ground and V+ labels instead of drawing them explicitly as wires. I've spent a couple of minutes looking at the circuit and I can't even begin to understand it. I'm sure other people with more experience with this sort of thing will be able to decode it, though.

oh yes lol my bad ... the green line is the V+ ... the Gnd is kinda the back "end" of that string of diodes lol ...

but i suspect the simulator simulated the circuit wrongly ... because the "boosted" voltage is suppose to be negative, but somehow, i had to reverse the position of diodes and ... i dont think it should give a positive voltage ...

That's a two-edged sword. With the diagram as drawn, at least you can find everything that is connected to ground simply by following the wire. If only ground symbols were used, it would be easy to miss one if you didn't look in the right place. While that may be unlikely with a small diagram and for the ground, for signals on a large multi-sheet diagram it becomes a significant pain and source of error.

In practice the middle way is often best: all subsections in a section of the diagram (e.g. amplifier, filter, driver, etc) have their grounds connected together so that you can see the unit. But separate subsections have separate ground symbols.

There are lies, damned lies, statistics - and ADC/DAC specs.
