New power chokes

By winding 13 turns, I obtained 25uH for a single choke. The saturation current is at least 310A.

There is still some space there, but I didn't have enough wire - in practice, one turn was more than calculated.

The cable is the same as on the toroid transformer - 50mm2.

They are certainly more than adequate for current applications. But who knows, maybe one day I will dare to more extreme power tests  


Now the chokes do not heat up like the previous ones.

They have one more advantage - they are super quiet. The previous ones on the E core, even though they were glued together, produced squeaking and sizzling sounds.


Here are the cores, controller board for size reference.
