Flyback design doubt

hello!

Is it possible to design flyback converter using toroid without air gap?

Thanks!

Yes! It is possible, although better performance is easily obtained using smaller cores + small gaps, using air gap give lower inductance but more linear. Also using iron powder cores works, but they give higher losses due to the bulkier windings.

Despite all of this, if you only need very low power levels and you have ungapped cores it will work.
