Method for converting HV (static) into usable low-voltage power.

[sm0ky2]

I had an ingenious idea to run two microwave inverters in series.

thinking i could drop 45VK down to 2300, then again down to 115V

little did i realize, these things are designed for 2-3KV, when i pump 45KV through it, it sparks all over the place and doesnt do its job....

Does anyone have some advice as to inverting such a high voltage?
specific type of wires to use? coil design, ect?

running the HV current through an intense magnetic field has a 'tension building effect' possibly could be compared to a variable capacitance, this may prove important in the process.
Paul Baumann called this effect "a magnetic choke"
the effect is basically a slowing of the static transmission, it appears to build up current as well but i have no way of measuring that for sure..
HV doesnt like my equipment....

anyhow:::   im looking to coil up a massive inverter something like 1k to 1

if such a thing is possible. and i need it to be able to handle 45K +/- on the HV side.

any help is greatly appreciated.

@sm0ky2,

Attached is a proposal on how to do it. I must add that I have NOT build and tested such a circuit. Knowing that most car ignition coils are designed to withstand very high voltage will make this circuit possible. Just remember to connect the car coil so that the high voltage winding goes to the spark plugs. The low voltage winding goes to the diode bridge. The high voltage capacitor MUST be of a high voltage type. If you bend the L part of the spark plugs outwards then you can adjust for higher input voltage.

Hope this helps you. Good luck.

@Groundloop,
Would your circuit work if the high voltage source supplied next to no current as with a Wimshurst machine? I know you're storing in the capacitor and then arcing at the spark plugs so it's time-compressed but I'd think (and you'd probably know better) the coil needs enough current to build up a magnetic field in order to work.

Steven Dufresne,

As I said, I have not tested this circuit, but I think it will work.

If you want to supply high voltage from a Wimshurst machine then
you need to make sure the two resistors has a high enough value
so that you do not load the Wimshurst machine too much.

The car ignition coil is used in a reversed order in this circuit. The
high voltage winding is connected to the spark plugs. So the C1 capacitor
must be a high voltage type so that the voltage can build up to a higher
voltage for the spark to go off. The currrent needed depends on the actual
size of the capacitor. The higher the Farad value the more current in each
discharge. But with a week input it will take longer time to charge the cap.

Yes, I think this circuit will work very well as long as you do not exseed the
maximum voltage the ignition coil can handle.

Groundloop.

this can be controlled to some degree with the 'gap' on the plugs, and/or adding leyden jars / HV caps.     

I've been using jars myself, because the only "HV Capacitors" i can get my hands on are from Microwaves. unfortunately - those toto are only rated for 2-3Kv,  the voltages im dealing with are WAY too much for those caps.

2 jars of opposite charge (should) act just like an HV cap in this circuit, i'll give it a shot. my mechanic assures me that the ignition coil CAN BE run in reverse to do what we're talking about, but he also cautioned about losses.
