Impedance matching transformer simulation
Here is an example of a transformer that converts 10Ohm load into 1kOhm
And the AC simulation result
From my understanding the source sees the transformer as an inductor in parallel with a converted ...

Designing of a ribbon microphone (sort of) output transformer
I'm currently working on an experimental string musical instrument. It isn't my invention though. The source of inspiration called Dvina has an unusual pickup system. It senses the current induced in ...

Is this an Impedance Matching Curve?
This may be a very quick answer, I had a test that was set up like this. The primary inductance of the transformer was roughly 0.022H and the inductance of the secondary of the transformer was 0.045H. ...

Keep potential difference fixed for transformer's output
I have a source consisting of V1, R1, L1, and L2 to which my load R2 is attached:
For the load, I have 10 or 100 Ohms.
1) R2 = 10 Ohms: Vrms = 315 V, irms = 32 A, P = 10 kW
2) R2 = 100 Ohms: Vrms =...

What is the impedance of a multi-tap impedance matching transformer when all taps are used at the same time?
So if I have an impedance matching transformer with two taps, one 8ohm and the other 4ohm, and both taps have a winding relationship so that the other side "sees" a 4kohm load, what is the impedance ...

What are the fixed values in transformer?
I am trying to understand how impedence matching works, but I realized I had some issues with basic transformers as well:
If the voltage and current is merely dependent to the input voltage, current ...

Audio transformer: What to do with an unused winding?
For the purpose of impedance matching and floating a single-ended, ground-referenced signal, I am planning to use an audio transformer like this one.
Here's the schematic from the data sheet:
My ...

Transformers and impedance matching
What I have learned: In a ideal transformer, the power in the primary circuit will equal the power out in the secondary circuit.
Impedance matching: if I take the turns ratio of the transformer in ...

Impedance matching with transformer and resistor
I want to drive a 8Ohm load with a tube amp(Push-pull 2xEL84) that needs a ~8kOhm impedance on its outputs.
I have a transformer that has a impedance turns ratio of 0,048. link
So if I just plug in ...
