Successful TPU-ECD replication !

[otto]

Hello all,

the last 4 days I didnt work at my workplace so I had a lot of time for my new tests.

I was always talking about my not soooo good controls. I did hundreds of tests.

I will be extreme short.

My control coils:

primary: 3.17m lenght, 0,5mm wire diameter
secondary: 16m lenght, 0,35mm wire diameter.

Control coil design:

1 primary coil
2 (TWO) secondary coils

All 3 coils wound at the same time (TOGETHER) NOT TWISTED!!!!

Controls 1" in lenght as in the pdf. Everything connected like in the pdf. I mean, Im using in this case only 1 control coil but pulsed with 3 frequencies.
In such a setup I have 1 16m long secondary doing nothing. With my indicator I saw a veeery strong "phase" on 1 end of my "free" coil and a "zero" on the other end of my coil. It was logic to connect my bulb to this free secondary coil.
Result: a nice shining 100W bulb.
In this way I have separated my load from the rest of the TPU.
In this way I have a veeery strong "phase" WITH A LOAD connected.
In this way I have almost a clear sinus wave measured on my bulb.

With my super scope ( Thanks Roberto and Gustav22, again) I measured the frequency mix: 170kHz - 190kHz.
When I tune veeeery slowly I can clearly hear a huuuummmm. Frequency mix: 178kHz!!!

Again in short:

Control coil with 1 primary and TWO secondaries.
Everything connected like in the pdf but the bulb connected to the "free" secondary, or to say it better, to the 2. secondary of the control coil.

I have to mention that this coil lenghts are made for a 6" TPU but Im using this control coil in a 15" TPU because there is a lot of heat, sometimes it happens I toch a wire...

Hi Otto:

Great! Are you saying the 100W is decoupled from the input and is just connected across the floating secondary with no DC path to zero? If this is the case, is it possible to measure the current with a series ammeter through the floating secondary?

Hello all,

@chrisC

exactly. But to measure the current would be a problem. The frequency is too high and my analog meter would not be a good idea. Anyway I will try it.

@ Otto

You need to measure the current on the input side with proper filtering. Measuring high frequency complex waveforms with either a digital or analogue meter is a no no!

This issue has been raised over and over again on this forum. I asked earlier if you intended to carry out proper measurements on the input side of your system using a battery as the power source. Can you confirm that you intend to do this and report the results?

Hello all,

@Clive,

I can only say that I cant exact measure the amps because I havent the needed equipment.
Of course, its totally clear that with my analog meter I cant measure the input and output power.

I will ask Roberto if he can make this job. I hope he has such meters and a battery.
