Circuit setups for pulse motors

[casman1969]

Just a note.
Charging slowed down considerably once I reached 12.96 on the charge battery.

There are still losses in the reed switch which are photonic, acoustic, and mechanical.

Whilst opto-coupling will give you far better accuracy, reliabilty, etc, than any other switching method, it may not be the best method for what you are all trying to achieve. Which is O/U.

Your edited comments imply that the reed switch may somehow be a better switching method than an optointerrupter if one's goal is to achieve overunity. Explain.

Hi Tropes,
"Explain"            I wish I could. Especially my last post, which, when I merely wanted to P.S. to what I'd already written, I goofed and deleted the original post altogether. Doh! 

Now about O/U......   A couple of posts back, I acknowledged that since I have never personally achieved O/U, I can only be considered a student in this forum. However, I came to this thread some time ago as you recall, and told you of a friend who seemingly had achieved O/U, even though only feebly.

I still think the effect was more directly associated with the spark in his mechanical switching, than the magnetic properties of the circuit. Whilst the inductive property of the coil is responsible for the large spikes in voltage, and so is indirectly associated with the self charging effect, it seems the sparking which is the result of the voltage spikes, is the prime suspect.  Robert Adams stated that the self charging capability (of his pulsed motor) was lost when semi-conductor switching was used.

I have read other experimenters experiences and supporting data and outcomes, who seemed to have achieved the same feeble possible O/U effects, and they all used high impedance coils (which accounts for low current consumption and losses in the first place), and mechanical switching, which produced sparks. (which may be accounting for the unexplained energy entering into the system) (or maybe not     )

Electric sparks are not like a normal chemical burning flame, which produce mostly stable oxides. Instead, they produce a mixture of ions, free electrons and some stable oxides. High energy ions are "PLASMA" and plasmas have a whole field of physics devoted to them.

High energy ions can be produced by electrical arcing (sparks) !  .....hmmmm   Tesla Coil.....lots of sparks 
Conversely, the presence of high energy ions and free electrons facilitates arcing.
Under certain conditions, it may well be possible that plasma helps to create more plasma by a cascading reaction.

The "filamentary" nature of plasmas contained in magnetic fields, revealing the "strange" two direction (double) spiral structure of high energy ion propagation has raised a lot of "conventional" physicists eyebrows lately!

Semi conductors by their very nature may prevent any "strange" double direction electrical energy manifestation, because they are biased to allow flow in one direction only. (an assumption of course, on my behalf )

MOSFET rectifying - - Shouldn't everyone be using this?

Anyone with advice/circuit/insight?  Has anyone done this?

I have reduced my rectifying voltage drop from 2.8 volts to 1.2 volts via individual schottky diodes - but it appears I can reduce it even further.......(Me wanna!)

Synchronous rectification is a technique for improving efficiency of power converters in power electronics. It consists of connecting a diode and a transistor (usually a power MOSFET) in parallel. When the diode is forward-biased, the transistor is turned on, to reduce the voltage drop. When the diode is reverse-biased, the transistor is turned off, so no charge can flow through the circuit. This way, a rectifying characteristic is obtained, without the forward voltage drop associated with diodes in the on-state.

Paralleling two MOSFETs reduces the losses further, whereas paralleling several diodes won't modify their threshold voltage.

Hi Hop
Could you re-post that one you deleted. I think it dealt with the use of Mosfets and I would like to see a circuit that replaces my TIP102 Darlington pair with a Mosfet. The circuit I'm using was given to me by Gyulasun who makes things simple for me and I posted it a while back.
