Hello everybody,
I started my own replication of Non-Inductive experiment. Now it is just few things which I have done. At first, in my replication I have used laminated iron C-shaped core. I am not sure, that it is good choice, but many of you can tell me that. Maybe it will be better to use ferrite or nanocrystaline core.
From first measurement I do not have good results. But I hope that I will progress soon. I tried standard rectifier diodes as well as ultrafast.
My schematic looks like this:
Some numbers of my system: (I tried to wind the coils quite precisely)
Coil L1 (primary): 26 turns of 0.8 mm (maybe it would be better more thicker)
Coil L2 (secondary under primary): 260 turns of 0.8 mm
Coil L3 (separately secondary on the other side of the core): 260 turns of 0.8 mm
Core: laminated iron core from old transformer - 30 x 21 mm (630 mm 2) cross section.
Inductances (on core):
L1: 1,73 mH, 0,16 Ω
L2: 190 mH, 1,43 Ω
L3: 190 mH, 1,42 Ω
Green - signal from generator (negated because of driver)
Purple - input current waveform
Yellow - L2 circuit waveform
Now I dont know if it is caused by the core material or the coils. I measured signal on L3 circuit, but it was very weak. Only pulses on edges of trigger pulse.
I hope that soon it will be looks better.
Have a nice day.
John.
