Coupled output inductor in BTL?

[81bas]

Sooo... No definite conclusion yet?

I would say, you have to use separate cores for all 4 inductors! 🙂

I agree with this conclusion.

Khron!

You MUST use separate cores, otherwise the aliens will attack the Earth!

 

[Khron]

Pah! Big deal, the planet's doomed anyway, might as well get the aliens here sooner rather than later. Who knows, maybe something good might come out of that 😀

But anyway, thanks for the verdict everyone 🙂 I appreciate the input and interest...

I have used Single Differential Inductor for AD modulation and it works very well🙂

 

[Khron]

Any details regarding that?

Differential, that means one winding starts "on top", and the other one "on the bottom" of the core, as viewed from above, right?

Hello Khron,

The winding senses are oposit of one another so that the core is magnetise with 2 fluxes shifted with 180 degrees forom one another.
