Partnered Output Coils - Free Energy

@Vortex1: I don't think he's getting such a big spike anyway, since he's underdriving the transistor. Hard to tell from his scopeshot though. In my testbed when I use similar drive levels to his (from comparing scope trace appearance) the main spike only goes to 500 volts or so, when the 10R (actually 11R for me) load is connected as in the EMJ-Meyer diagram.

If you really want to kill the spike just put a modest capacitor between the cathode of the catch diode and the emitter (0V node) of the switching transistor.

Here's another example of a proper Caduceus coil. Unfortunately there's no demonstration in the video, just the nice coil is shown.

Could one describe these coils as "self-bucking"?

Demonstration wanted? Here is famous part of Lithuanian experiment...

@TinselKoala,

"If you use MOSFETs, you don't need the current sharing resistors at all, they can just be parallelled 'out of the box'. MOSFETs have negative feedback 'built in': if one MOSFETs gets a larger share of the current, it gets hotter which in turn increases its resistance and reduces the amount of current going through it. This is why MOSFETs are usually preferred for applications where multiple transistors in parallel are required. However, BJTs are easier to built into current sources as they have fairly constant current gain".

Hi guys, Some help needed here

EM state the best result he gets when he has the primary as an LC tank?  I have made a time ago a circuit ( ref. Mr Kopecky)  , which suppose to sustain the resonance.  I am not very good in electronics, Can somebody experienced here to take a look at it as I am not sure if it is working right for me. It heats one Mosfet more than the other and also I want to ask- is it necessary to use -12V on the comparator? Would it work with just GND instead (that's what I use at the moment) The cuircuit picture below.

Next - If the device creates or double the E field, for some reason I must think about E-Stress capacitor(or device), I have made two sized versions and non of them worked - maybe it would with a bit different configuration of winding as we discuss here?

Also I am translating the document of Mr Brovin- It is around 13 pages- pain in an ars- but it is quite interesting and also related to the principles we talk here about?

A quotation without a reference link? Shame on you.

Read and learn, if you can, these technical papers from MOSFET MANUFACTURERS and the forum of the major parts supplier:
