@@alexkoteles Frolov transformer is even better where it uses a single closed loop core as the primary winding directly wraps around the two secondary windings. But doing so reduce output power to Zero. Hence, capacitor is needed.
Hi Lukie Maybe if left secondary "closed loop" core is wound or connected LHR while the right secondary core is wound RHR then the primary over the top of each is wound sort of figure 8 pattern in between the secondaries and connecting them together, so now more induced area of winds for more power produced and also no cancelezation of power from opposite wound coils? Just thinking....
Hi Alex Yes, this design taken from Patrick Kelly's version of how a Thane Karl Heinz "BITT" transformer can be constructed using a stock 3ph transformer core, then the shunt bars added on to it. Other ways to do it....baric idea and purpose is AC reactive power will be seen feeding primary (more pure the reactive power the better) , and at same time, real power is to be seen feeding the load from the secondaries.. No toroidal coils you this way, so BITT transformer not such good description. Hector likes to call these hemmorroidall transformers, as sort of a joke. the hemmorroids the shunt bars.
Good one funny thing...a month ago I took apart a old 24 volt power supply. Found on the curb someone had scrapped. Found the transformer had 3 windings. A primary where the 110volt line came in. 2 secondary windings one on top of the other. Double 14 gauge windings for the 24v output side wrapped on top of a 20gauge spool of wire. This inner secondary was only shorted out through a set of capacitors. 2uf 720v. Feel this shorting out of inner secondary helped establish a larger emf for the current draw for the 24v output set of windings. Might try winding the coils over a smaller winding shorted out giving a larger Emf that is established in the coils when energized with the core. Its all about the "field"
Interesting, I would call it a "linear transformer" as sounds like long core, with primary at one end, and then two secondaries on "top" of the primary, and one secondary is shorted out (connected to) a 2uf 720V cap that coil being shorted out is what is interesting - Hector's "transvertor" is more or less a 3ph transformer, with coil A the primary coil C is the secondary to load, and the coil B in between is supposed to be "resonated" with capacitors but not actually connected to A or B coils.....simmilar to what you found....Hector says you need to tune the crap out of a transvertor, with HV AC caps in series, in parallel, much bench work needed to get some good results....variables in juggling act of everything reacting to everything and everychange is the voltage input, the load, the frequency the pulse width and especially the cap values. Apparently there is a cap size that will make the cap work like a direct short circuit, which can really boost the voltage going into a cap maybe that is reason for that 2uf cap you found I dont know......
Adding to my first comment that was posted, just ideas. so it seems if the secondaries were wrapped over another coil that was shorted out through a capacitor. there would be a stored emf in the coil that was also helping the emf in the core. also helping the phasing and establishing resonance. This stored emf in the under wrapped shorted coil would be able to be drawn off in your output secondary output coils. Just thinking out loud. been trying this myself with good results.....
Hi Moon I made a "BiTT transformer" (for lack of better word) made of green enamel coated florist wire core bundled up thick so supposed to work like laminate steel. I bent it around to crazy infinity symbol shape X 2, (sort of) it had curved shunt bars that connected tothe backends of the secondaries, not the "tops" of them as seemed like that would be the natural flow of currents... Didnt work that good, probably the florist wire could not carry as much magnetic current as steel laminates from transformers will carry but thing is, I wrapped "additional winds" all around the shunt bars, and found when I shorted these winds out, the draw went down a bit and the output went up,,,,I made video long time ago here it is: "fairly interesting"....I was not checking the power factor and phase shift with scope so the in and outs of V X A is only what meters say it to be... you need to know power factor in AC to get real watts input... Anyways very interesting how winds around the shunt bars being shorted improve performance: I still have this transformer in a box on shelf.... ua-cam.com/video/saJ-l1Kg6hE/v-deo.html
It's more efficient to just directly wrap the primary windings around the two windings. You save resources as only the single closed loop core is needed.
The point of doing it this way is to loosen the coupling, to prevent back emf from destroying resonance. I am told it helps to have a permanent magnet in the gap, above the primary (haven't tried it myself, tho).
@@paulshields1883 Permanent magnet saturates the core, which isn't suitable for transformers but good for pulses. Back emf destroy the dipole, not resonance. You need to add capacitor at the output side when back emf is completely destroyed. No real output power. Primary winding fully becomes an inductor.
Hi Paul The backemf lurches itself back into the primary and lowers its resistance, and lower resistance causes more draw in the AC c😮urrent input. Backemf only will occur when forward currents flow through the primary coil, and the idea of the shunt bars is they work like a magnetic diode, in letting the forward current pass from primary to secondaries, but the backwards flowing "backemf" chooses the path of least resistance, which is through the shunt bars into oppoSite secondary. The backemf magnetic current avoids a clash with the forward magnetic currents when polarity of the AC signal to coils switches polarity right after the sinewave peaks of AC signal and chooses that alternate in 7 path through the shunt bars. It is very fickle to get to work right, the resistive or inductive load chosen as well as the voltage input chosen as well as tuning capacitor values will decide the performance or lack of performance. Good performance is when the primary has a 90 degree or near 90 degree phase to its AC "reactive power" input and the secondaries output is "real power", with no phase shift at all between the current and voltage.
Hi Lukie Do you mean a core with just two legs, not three, and the secondary coils wound around each leg, and connected either series or parallel and the secondaries connected to load? Then the primary wound "on top" of these secondaries...does that mean a single primary wind that stretches and wraps and winds across and around both secondaries,? Or do you mean each secondary has a primary wound around it's outside, so actually two primaries? I can see how one secondary wound stretching across both secondaries would allow backemf forces to transfer via core material into the other core leg if it wants to choose that path and not into the primary winding..,.is this what you are thinking,? There is now no primary core leg to transfer magnetic currents into, only the secondary core legs...it sort of separates or isolates the electrical backemf from the magnetic backemf and the magnetic back emf flows through the core material and would "dominate" while the electrical back emf would be consumed by the magnetis backemf, and so the electrical backemf just does not exist anymore in the electrical output...(?)
At 5:03 I meant to say it goes "over" the primary (not the secondary)
