I've a question regarding impedance matching using a toroid transformer.

I have a source, 50kHz with an internal resistance of 50 Ohms.

I want to connect this to a 1000 ohm resistor and get maximal power transfer.

(no real goal to this other than some experimenting with electronics)

As far as i understand the winding ratio of the transformer (Ns/Np) should be equal to root of the impedance difference of the loads ( sqrt(Zs/Zp) ).

resulting in approx Ns/Np = 9/2, which I've wound on a ferrite toroid (2 turns primary, 9 turns secondary).

When connecting the source and the load, the resulting voltage at the primary side of the transformer drops to almost 0.

Which does seem to make sense, as I've more or less shorted the source with only two winding.

So my question is, is next to the turns ratio (9/2) the absolute number of turns also important here?

Should I wind the primary side of the transformer with such an amount of turns the the impedance at 50kHz is also 50 Ohms?

This would be 16mH -> about 292 turns primary? (and 1314 secondary)

Or am i missing something else in my approach?

Thanks,
