Agentgates´s TPU setup with strange wavehill hump

                  i believe those derivations may be incompatible for the differential changes which take place on a curved spline...though they are negligible at small radiuses, they become substantial with larger ones.

@minde

Have you made a coil , i believe not .

The problem i see with your equation is that it will not permit making more the few turns before you get to the exact same position , overlapping the turns.

You will see if you build it.

Is this the effect You are observing driving your TPU?

experiment description: Tpu with one driving coil, ONE TURN of collector loaded with 2.2ohm/3W resistor and white LED parallel. Diode light is very bright, voltage measured on the 2.2ohm load You can see on the scope. Input power about 12W, output about 1W. Still far from from OU, but for me there is something goin on in this device (Im an electronic engineer). Btw, this setup IS frequency dependent. The highest power occurs when freq=33kHz

Try more turns maybe 2-3 secondaries of 2-6 turns each....see what happens and also what is the voltage input?

Hi Marek,
is this the scopeshot across the 2.2 Ohm resistor ?
How does your input voltage look from across the input coil
at 33 Khz ?
Is it a 50/50 duty cycle square wave ?

Hmm, the positive hump wavehill is mysterious there.
Please try with different load resistors and without load resistors
and with more turns and please post more scopeshots.
Many thanks.
