Agentgates´s TPU setup with strange wavehill hump

[Mk1]

@agentgates

Keep the good work , i have so say it is a pretty good design transformer , i use it on a joule thief circuit , and it works great , almost like a regular toroid .

The coupling  between the coils is great . and that even at less the 1.5 volts.

So now i am testing different things , on my first device i was getting about one volts per secondary turn now over 7v.

I am waiting on a signal gen to get into the real stuff .

Thank again !

Ps don't mind Marco he is the boss of the tpu circus . I hoped that hiding the tpu tread in the ou prize helped keeping it low profile , before all the naysayer picked up the sent of controversy .

Mk1  Thats sweet that you got it going with a jt.  So the output is dc? And what freq are you running at?
It is a good thing to know an alternative to running one.
You said it works like a normal toroid. Does that mean that the output current goes down as the voltage goes up?
I have an alternative also that I am going to try. My self oscillating reed coil setup. Im going to set it up so the bemf spike is sent to the primary. It will be around 250v. I plan on running my washer and dryer with it. lol  I dunno what is going to come out.  Ok  gunna fire up the twizzler.

Mags, I know the questions for Mk1 but I would answer some of those things I can:

And what freq are you running at?

This device is not freq sensitive. You can fire it with either a high resistance pull-down res on the FET's gate and touch the gate with your gate voltage output of the PSU.

Does that mean that the output current goes down as the voltage goes up?

Your output (both voltage and current) should depend on the diameter and length of your secondary, also the voltage you put on the primary. When you increase the primary voltage the hump is slowly growing out of your 0 voltage line and going higher and higher. After a certain level it does not make a difference whether you go above with the input because the secondary gets magnetically saturated. This is the maximum voltage you need on the input to get the maximum out of your output.

Later when you will do it with 3 primary in 120 degrees out of phase you will noticed that the increasing of input voltage also gets the spikes a bit closer each other. Approximetaly 100% increase on the input voltage decreases the pulse delay with 20% while the pulses go higher and higher.

UPDATE1

If you're using CRO please read Lindsay's message as he experienced something with it that can cause failure if you ignore.


UPDATE2

Ok Gentleman I glued the last thing on it. Hope it will be as solid as concrete and then pop the primaries on tomorrow. Now I drop a nap and will be back sometime at GMT 11AM tomorrow.

Take care and good luck until then.

Kind Regards

First of i don't have a scope , so as far as freq goes i used a basic jt circuit
so range of freq it works at looks to be the same as a toroid i usually use .

Now what is it , DC OR AC , lets say i don't read anything on the secondary with my meter unless i use a bridge , but that said , with out diode a led light only in on direction , so it as a dc feel to it , but is seems different some how , i wish i had a scope .

I tried 2 phase like the regular center tap jt each going to make an opposing field , got voltage out up to 7 volt per turn , but that is 18 turns push and 18 turn pull . I also use a toroid to make a pull pull try , by making one turn of each 18 turn coil one the toroid one in reverse so the jt circuit would still work , i got about 10 v out of 6 turns .

Also i made a 3 secondary one , they worked pretty good .

So in the end it works in the usual jt parameters , freq ,multi secondary .

I got other winding idea i will not discuss here , in order to keep on subject .

But so far i see a alternative to the regular ferro magnetic toroid .

Btw i don't have amps reading i got a bad fuse.

Edit i did get higher output volts with higher primary turns , i am at 18 i am shooting for 36 tonight most likely early morning.

Tony it's a bit confusing talking about phase degrees with square waves. I assume that 120 degrees out of phase means that the next pulse starts 1/3 of the on time later?
