Last night I had a great idea before i fell to sleep.
I just remembered. Luckily!
A coil, when pulsed, creates a back emf when the pulse stops. this pulsed coil can bring a parallel coil in to resonance via its magnetic field.
The back emf also can make a resonant wave, when we pulse it directly into a (resonant) coil.
If we want both resonances to add up their voltages, they need to be in phase. Thsi means the back emf needs to be at the start of the [pulse, to do this, we need to buffer it into a capacitor and discharge it at the start...
There is an easy way, where we dont need to buffer the back EMF into a capacitor.
If we use a 50% duty cycle pulse, and we make it a positive and negative pulse. (not a off on off on. but, 50 %positive on, 50% negative on)
The positive pulse is directed into one coil(A1), creating a magnetic field with back emf, and it lets a parallel coil (A2) resonate.
The negative pulse is directed (diode, or the post i made a while back) into another coil (B1), again also creating a magnetic field, with a back emf, and it also lets another parallel coil (b2) resonate.
So this is a double system, where one is on while the other is off, and vice versa.
Now the beauty!
The back EMF produced by coil A1, is produced at the same time, coil B1 is pulsed/magnetised.
So, the back emf of coil A1, can be directly injected, into resonant coil B2.
And vice versa!!!
the two magnetic resonant coil sine waves, are getting a back emf resonant sine on top, and the voltage is doubled, so the magnetic field is also doubed!
No capacitor needed, no switching needed. Man, this is a good idea.
But... it needs to be put into practice.
The polarities of the back EMF need to be correct, so it needs to be figured out, how to inject the back emf from the positive pulse into the resonant coil of the negative pulse.
Maybe this is not possible, but i think is can be. by using the other end of the resonant coil to ground we can alter the phase.
OK ok... its just an idea. but It would be so nice, to direct the back emf straight into another resonant coil, without the need to store it first in a capacitor.
Both resonant coils can then be used to resonate 2 output coils, that are out of phase, so the output gets doubled again...
But... Its still based, on some assumptions. this needs to be worked out.
