Burning wires and Mosfets
It would be very encouraging to find any diagram such as you are making here that I know does not start a fire when it is connected. I am not asking for a full working O U layout here. I just don't want my bread board getting burnt marks on it for a circuit that looks good but somehow "DEAD SHORTS OUT"
I understand that you are a beginner Dave and thank you for sharing your speculations of possible unknown running circuits but may not be.
When you get one running make sure you throw up a red flag or a white flag to designate the one running on your board. That way I can try it also to see if my circuit performs like yours does "A replication"
Great circuit generator dude

I have to think it out, set up a plan.
I'll build it soon

and by all accounts(as in multiple impressed replicators) this is a weapon of a desulfator/charger.supply voltage is higher than charge voltage on this one.Attached FilesLast edited by voltan; 11-08-2014, 07:11 AM.

This is a very interesting circuit has it been tested.
Reminds me of what Dave and Matt are doing in the 3BGS thread.Half of the Answer is knowing the right Question

I cleaned up the schematic some
We'v been taught to look at schematics in conventional current flow but if you look at it from an electron flow perspective the circuit makes more sense.
When the transistor turns on electrons flow from the neg side of the 24v battery into the coil and ultimately into the neg side of the charge battery.
When the transistor turns off the collapsing magnetic field sends a pos charge to the pos side of the charge battery through the diode.
The charge battery is getting hit on both sides.
There are two sides to every story
Follow conventional current flow but also look at the schematics in an electron flow perspective and you may get a little more insight to whats happening in a circuit.Last edited by Dave45; 11-08-2014, 10:02 PM.Half of the Answer is knowing the right Question

Current is a consequence of electron flow, so even though the coil is connected to the neg side of the charge battery we still get current flow because the 24v battery is forcing electrons into the neg side of the charge battery.
If electrons are flowing in one direction current is always flowing in the other.
Thanks Voltan for bringing this to my attention I enjoyed studying it.

With neg electron flow we get a pos current flow
I wonder can we create a pos flow and if we can will we get a neg current flow.
If we flipped all the battery's diodes and the transistor
Ya never know guess I'll have to give it a shot
I think I'll use a p channel transistor
