Otto`s replication of Steven Mark`s TPU

[MeggerMan]

Hi Otto,
The 400V spikes you are seeing, is this measured across the 12V 5 watt lamp?
It is possible to apply any voltage to a 12v bulb as long as the duration is short.
But to get that kind of voltage you would also need a fair bit of current.
It would be interesting to see what would happen with a bulb with a higher resistance.
You may get an even larger spike.

Does is matter how thick the wire going through the 50 turns is?
For example, could you try a 15mm or 22mm piece of copper pipe?

Regards
Rob

Similar oscillator circuit:

Not pulses, but similar. 

I know of one that turns 5v into 170v pulses and will scan and post tomorrow.

Hi Otto,

I'm still here and I am going to try your experiment again. Could you tell me how much input current your circuit draws when it is running. Until now, I have been using a DC power supply which is current limited at 0.5A, so if I'm not pushing enough current into the system to get it working, that may explan why I'm not getting the same results that you are seeing. In case the current input is the issue, I'm going to string a bunch of 9V batteries together to use as the power supply.

God Bless,

Hello all,

congratulations to Ronnotte!!!! Im happy!!!!

In the picture you see a 25W bulb shining. Its not at full power because I would blow my scope.

Frequencies are in kHz .
The TPU is made with 2 special wound controls each of them on a collector with only1 turn of lamp wire.

Because Im really tired I dont want to respond for a while. DONT ASK ME ANYTHING. I WILL NOT RESPOND.

Here you have a link that somone of you alreday postet not so long ago.

With this link and my little 50 turn control coil youre now able to built a 100W TPU.

Now will also Ronnotte have much more success.
