Nope, I'm drawing the line at mains - this has to be powered by a battery so it will need an oscillating circuit and, potentially quite a pokey one.
I'm not too sure why 240VAC scares me more than 2kV but there you have it
But it would make it a lot easier - no oscillating circuits etc etc. Hmmm...
I imagine the initial current drawn into your cap bank must spike pretty high?
Is this about right?
Q=C*V=.0001 * 500 = 0.05
Q=I * t. Using t=7 we get I = 7mA - at the 500v end = 7mA * 500/24 = 0.15A - not that high - I guess it spikes then reduces
Have i got that right - 150mA doesn't sound too punishing for a christmas tree light transformer yet you say they get terribly warm
Do I need to limit the current being drawn to minimise the transformers burning out?
If so would a hefty resistor in series in the 24VAC circuit do it or would I need to do something more clever?
I should have listened to those inductance lessons! (Would I need to avoid a wire wound resistor for example)
I like the idea of not needing the doubler circuit - though, for now as a proof of concept I'll stick with the bits I have to hand. For future reference what was the module - £20 is hardly a lot for so many volts and I'm sure the local dump will let me have an old microwave
