Can you post fixed circuit ? could the frequency of this circuit be changed ? Does the output voltage depends only on transformer ratio or also on frequency of pulses? I'm looking for a way to make variable DC power source replacing variac + diode bridge. Something which can output 30-190VDC from the input of 230VAC, at 35W - 50W.

A general purpose power supply can be purchased or built. Unless you want to build for building's sake, I'd go hunt for what you want off the shelf. Look for something like an Agilent 6614 or equivalent used or new from an Asian supplier. for example here is something in that power range that does 0-100VDC at 40W: http://www.ebay.com/itm/HP-Agilent-6115A-0-50V-8A-50-100V-4A-Variable-Precision-DC-Power-Supply-Unit-/111477472334?pt=LH_DefaultDomain_0&hash=item19f4933c4e

Ok the proof is in the pudding
I hooked the two circuits together but without the output cap
it works, the one watt led will blind you, still seeing spots

came on guys , is there nobody interested in energy amplification anymore ?

let us back to school, in link provided bellow,
look at the table and compare Power primary(Pp) VS Power secondary(Ps) , hmmm .....

114w in and 395w out. Thats odd.

will look into it later

Tito once said he was using ac to pulse dc
How about pulsed dc to dc
I havent tried it yet, still thinking
I remember something Steven Mark said, he said he could see the 5v in the output, he was talking about frequency's.

Works

I noticed I could run the load on either side of the bifilar coil so this will be the next test.
pushing and pulling on the load.

Hi all,
one example off power amplification https://www.youtube.com/watch?v=qW2YVh044JI.

Cool

I could hear the relay when you connected it up. Would you we willing to start a thread about this?\Bob

Hey Dave
Elegant simplicity

Looks like you're feeding the bemf back into the primary. If you were feeding the secondary's bemf thru a diode to a new coil on the toroid, I wonder if the new pulse to the core would create a standing wave which you could draw from with a pickup coil.
I really like this.

I was playing with the mazilli schematic trying to turn the current flow make it run from outside to the inside and this is what I came up with.
I havent tried it yet but thought I would post it for review, it should take the bemf from one side and feed it into the other, but it needs to be tested.

looking over these last pages, Tito did point to some images of switching supplies. He also said once, from the way I understood, that to make a secondary of just a little more turns than the primary. From that, possibly the secondary wire should be a bit thicker, just a bit depending on number of turns difference, as to possibly get the primary and secondary resistance similar or even lower than the primary.

Like if we have a primary of 20 turns, and a secondary of say 25 turns, if the sec is wound using larger wire, it can carry more current than the primary, not as with conventional turn/wire size ratios we normally see. So if we hit the primary with 20v pulses, and we get 25v out, what would the current capability of the secondary be compared to the primary input current?

Just something to think on.

All the switching power supply stuff is great. But we need to figure out the 'twist'. The 1 item that allows for more out than in. I lean toward transformer configuration. Without the twist, all these other things are less than OU, even though some are very close to U. Use any of the circuits as input, but the transformer config is the key I believe.

One more thing. I tend to prefer a switching circuit config that when the primary is powered, the secondary has a rectifier config that does not conduct sec current till the primary power is disconnected. This allows the primary to have a consistent input no matter sec loading or changes to the sec winding. Gets rid of mutual inductance between pri and sec and the sec only draws off of field collapse.

Something for the motor builders

A friend and I have gotten into the small quad copters a bit. The tiny ones fly soo well as compared to small helicopters, though there are small helis that cost a bit and fly mint.

Looking into them a bit, some of the motors are coreless motors. These tiny things really rock. So I looked into the coreless thing.... Some show comparisons to traditional core motors and explain the advantages of coreless....

http://www.citizen-micro.com/tec/corelessmotor.html

This one has an interesting idea on reducing brush damage....

And here is a diy guy... Hea and his brother made a car( link above on that page)

http://michaelnorcia.wordpress.com/motors/

I have a disassembled pancake motor from a car cooling fan that uses this principle. Ill find the pics and post.

These motors can be 98% eff. So if we want to reduce losses, this seems to be the direction to go with.

The pics below, from the links in my last post, show an armature and the other pic is of general parts and how they are assembled.

The mag is diametric, poles through diameter. So these could be converted to where the magnet is the armature/rotor and the brushes can be eliminated and controlled with a driver/hall sensor triggers.

So in the pics, the design is where the diametric tube magnet is stationary with the case and the armature slides down over the fixed mag. The mags field once out beyond the windings sinks to the iron motor casing as a path back to the other pole of the mag. Simple genius really.

So these may be very good generators also. I wonder if the motor casing were a bit wider and add a bigger ring magnet between the outside of the copper wire armature and the larger case if the motor would work any better. More dense field for the windings to work with.
