Agentgates´s TPU setup with strange wavehill hump

[wings]

" Conclusion from this point is that oscillation and spikes occurring while driving with single MOSFET are needed to achieve big spikes on the secondary, and because of transforming input wave shape to output, it seemed to act as a regular transformer (of low efficiency due to lack of the core)

The same for me, it seem that spikes are needed to provide some effect on the secondary.

My suggestion is to drive the primary with a Bedini oscillator that have fast transients.

Update:
with the obvious warnings of this operation
removing the part from diode bridge ....

@all

I am still experimenting with the coil it self , on a jt .

I succeed in lighting a filament bulb brighter than on the source battery .

Also noted fact for jt fans , usually you get either power from the secondary or the basic led , but in this case both .

The main pulse from the jt is not affected , by putting a resistor on the secondary or even closing the secondary.

I made it from a Toilet Paper  roll so i call it a TP Unit  .

Whether this is marks tpu or not , it sure works better then my usual jt.
And worth investigation.

Nice job MK1!

What is the output and input power levels?  Also what is the bulb rated at?

[wings]

Some test using 0.06 mm primary wire close to 43 US gauge, and 0.75 mm secondary.
Max primary current 0.4 A spike on secondary max at end of square wave.

As you can see I was not able to light led.

disconnect the loop you created with the cro ground input



monitor output only  ..no load for now

reverse the cro leads

zoom in and out



Edit ..my post spelling changes after i post it???what the
