Bemf Boost and Buck converters

Buck Converters
Boost Converters

A possible circuit, not tested.
Three or more chokes could be used with sequential and synchronous switching.
The load is mostly fed with bemf.

There's an animation about half way down the page that shows current flow expansion and collapse of the magnetic field that is really helpful for us rookies

Yet another untested circuit
I'll get around to testing them, then I'll edit the post.


Edit: This circuit works ok used a bifilar winding on a flyback core with a feedback winding to run the transistor.
Powered up a 1w led using a AA battery that had less than 1v charge, very bright.
I may scale this up in time.

I noticed I could run the load on either side of the bifilar.
Next test Im going to push and pull on the load.

hi dave.this is the most efficient setup i have tried so far.credit goes to mr Qantstuff for diagram A.the diode between the - rail and vr1 has a forward voltage drop around .65v( i use a fr302 and a schottky 1n5189 in series).this keeps Q1 around the conduction threshold regardless of input voltage and vr1 adjustment which controls the base current.this approach provides crude regulation and makes for hard and fast switching and higher operating frequencies than usual.
next trick is both windings and the battery supply power to the led.the red arrows show the path of emf when the field collapses.
diagram B is modified to run off small solar cells pillaged from garden lights.the output charges 4 aa nimh cells in series.here only 1 winding and c1 push on field collapse but i got more efficiency this way because d2 is another 1n5189 with less v drop(.2-.3v), than going through d1.
input is around 1.5v when the sun is out and output is up to about 5.4v so i added another winding for diagram C.this helps a little bit. 1.5 v 50ma in=5.3v 11.5ma out.that's over 80% which is decent for a simple diy converter,and that's with 2.2 ohm meter shunts and vr1 tuned aggressively,622 ohms,for max output current.with these circuits i have measured efficiencies around 85-86% with vr1 backed off but as it's solar powered why not go for max charging current.
next step is to try diagram B with the third winding,L3 piggybacked on to L2.i need more solar cells to get say 80-100 ma at 1.5 to 2 volts.this will increase the charging current to the battery pack.
solar panels have a different voltage/current curve to other power sources.for best performance they need to be matched to the load with the right series/parallel combinations.
t1 is a mje340,hfe measures 75. c1 is 25v 4700uf,presumably low esr from a SMPS. inductor is a small ferrite torroid with 16 turns each winding.

Hi Voltan
Cool, I will study your circuits

I found I could run the base of my transistor from the end of my bifilar winding but not to start, to start I have to use the feedback winding then I can disconnet it.

Interesting circuits, and fun to play with, I need to order some panel meters in the milliamp range to get better measurements.

Dave when are you going to test these? Alot can happen in the realm of imagination. Proof makes something work.

Sorry

Matt

Iv tested the simpler ones
I have to think it out, set up a plan.
I'll build it soon

I know Iv posted alot of schematics lately, I had an idea and had to run with it, this page is like a notebook.
Iv learned alot studying buck and boost converters I not only study but I build and test too.
Something important I have learned, current is a product of electron flow


Watch the buck converter simulation Buck Converters
When the transistor turns off the current takes a path through the diode, if current actually came from the pos of the battery when the switch turned off the current would continue to feed into the battery until it was exhausted.
But it doesnt it goes through the diode this bugged me for awhile until I put it in the perspective of electron flow.
We have to build our circuits to accommodate both.

Im sure you folks that have been at this for a long time already knew this but it was a revelation for me.
I continue to learn study and test.

All the Best,
dave

If we look at the first schematic in this pic the one thats voided, according to conventional current flow it should work when the switch is on the current moves from pos through the coil to neg when the switch is off the current moves through the diode and cycles through the coils,,, but it will blow the transistor and here's why.
There is no alternate route for the electron, when the switch is on electrons move from neg to pos when the switch turns off there is no alternate route for the electron and the transistor is blown.

The second schematic allows for both electron and current flow
When the switch is on electrons flow from the neg to the pos and as a product of electron flow current flows from pos to neg when the switch turns off the electrons move through the diode and current enters the alternate path and both cycle through the windings.
I say both but actually its just the electron the current is a product of electron flow but both have to be accommodated when designing circuits.

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

Mike

hi dave.that last one looks like a stungun/taser circuit.
i haven't tried this myself, but it's claimed to be very efficient.

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.

Hi Voltan
This is a very interesting circuit has it been tested.
Reminds me of what Dave and Matt are doing in the 3BGS thread.

I added a valve to the schematic this should allow C2 to siphon electrons from the ground circuit as its being charged.

The problem I have in testing this circuit is Q1 needs to be ran at high frequency and Q2 needs to be ran at 60 hz.
I dont know will have to think about it awhile.

hi dave.that's a yes.to clarify the bit in brackets,plenty of people have replicated this and given it glowing endorsements in their feedback.it's a beast.just google re-emf charger. cheers

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.

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

One crazy idea follows another
I went to take a break and had to come back
Im sure this will never work but I couldnt help myself

Crazy will never work

hi dave.well spotted.now that you mention it, battery swapping as per 3BGS might turn out to be a good thing to do with this.i read most of that thread recently.

Maybe the guy's that are working on the 3BGS need to turn their battery's around.
