The Binocular Core Transformer or twin core
I glued two toroids to make a binocular
A different view of the cores.
9 turns make 98uh.
The twin toroid and two binocular cores. The cores come in a range of sizes. These are all the same material.
The twin core 1 turn gives 1uh.
The large binocular gives 1uh. same as the twin core.
The small binocular gives a little higher inductance.
I wound a 3 turn primary and a 9 turn secondary. The primary reads 4.8uh.
The secondary is 38uh.
So the choices are twin core or a dual aperture. I have wound the large binocular so I will try it next.
