High Frequency Transformers

A little video I made about my research work. As electronic devices decrease in size, the power supplies and transformers also get smaller. The transformer design equation says that the frequency must then increase. But at high frequencies, skin depth losses occur in round windings. Replacing with foil windings reduces this, but then you get proximity effect losses. There is an optimum point at which these losses are minimised.

true but, what's the point with the stupid doll

I think Tesla way back did a lot of research in HF electricity. Some of his coils were without solid cores at all, which allowed for efficient operation at much higher frequency.

It seems much more economical to make HF-transformers, even by just going up to 400 hz.
