Chinese Oscillator and MOS FET Driver, Hardware experiment

Packing the PVC core with magnetite composit would be much simpler then shaping that rectangular job right?

There its really not much to this build; The coils are household wire! What kind of advantage would there be in building a ferrite core with blocks? Permeability can be controlled with particulate ratio.

Yes this is true. Only the total ohmic resistance will change. I used ferrite rings for this task.

What is your opinion on the voltage across the 28T coil? Should it give a voltage level depending on the turns ratio, or it also depends on other factors due to the in series resonance?

That shift in voltage could be caused by incorrect grounding of your oscilloscope. How is the scope grounded?

[Jeg]

Yes it is grounded but now that you say it i will check again. My Rigol's probes are all grounded.

Ahh do you think it is because we have a zvs driver? The primaries are in a parallel tank circuit which gives rise to voltage. Perhaps that is the reason.

If you are reading voltage off the 28T coil, that coil itself needs to be independently scope grounded to get an actual measurement.

Yes i have connected one side of it to the negative of the pwr sup and also to the ground through the probe's alligator clip if this is what you mean.
