Okay, here's one for you guys...
We build a transformer that has two primaries and a single secondary.
One of the primary windings has many turns for accepting a high voltage
input. The other primary winding has only a few turns of thick wire
for accepting a high current input. The secondary winding we will have
to calculate the turns and wire size based on our needs provided this
half baked idea has any merit.
With each primary winding we calculate its inductance and connect
a capacitor to one leg of it and a power source to the other leg, then
from the other capacitor leg to the other power source leg. So what
we have are two series resonant L/Cs with mutual inductance via the
transformer core. We adjust the capacitor values so that both L/Cs
run at identical or nearly so frequencies. Each power source is
relatively low wattage--one high voltage; the other high current.
If we can get this far without running into some kind of physical
impossibility, what would the secondary see?
Based on transformer turns ratios, this scenario is a bit of a mind
screw for me. We have step-down which should increase current
and we have step-up which should increase voltage. Best I can
tell, the secondary should only see the changing magnetic field in
the core and be oblivious to how that field got there. So what I
wonder is, would the secondary only see the combined wattage
from the two input sources? Or could it see some multiple?
Know the answer already?
Then suppose we have two separate cores with the secondary
wrapped through both of them. Would it still behave the same?
Again, half baked idea yes, but what I'm striving for is some way
to take advantage of turns ratios where the weakness of one
power source is made up for by the other power source. Maybe
it would require some kind of switching to lock the current in
the core as the energy transfers between L/C components.
Could be a chicken and egg problem where we do not know for
certain what the dependent and independent variables are. And
of course, it's not nice to fool mother nature.
