Hi,
Did anybody here, look into the back emf of a partnered (bucking) coil?
I'm researching the bifilar pancake coil as described in tesla's patent 512340. I find it's huge voltage rise at its resonant frequency intriguing.
To get the coil into resonance, I want to use back emf. because I believe these are the impulse currents used by Tesla. And it just makes sense.
But to use the back emf from a normal coil, creates a impedance matching problem, that results in a bad power transfer to the bifilacr coil, due to the high impedance of the b emf coil (source) and the low impedance of the bifilar coil.
Bucking coils, Or partnered coils, have a very low impedance due to the inductance canceling out. But they still produce a strong Back emf pulse.
I've tried this as shown in the attachment. The IGBT is a 12V powered switch that is controlled by a pulse generator. The bucking coil, is charged, and then opened up, releasing its stored field energy into the bifilar coil, with a single wire. And It works. The pulse stays strong while the resonant sine wave the resonant bifilar coil is high in voltage.
This however is not ideal. The bucking coil stays connected at one end to the igbt circuit. Ideal would be a double switch, but for now, this is what I have.
The whole Idea, is to create, high voltage pulses, to get the resonant sine wave high in voltage.
I then rectify the standing wave, into a capacitor.
I want to find out, if the resonant voltage is high enough, if there is a gain, from the back emf pulses, to the resonant sine wave's energy.
