magnetics question

jlarkin · 2022-04-06T15:53:22+00:00

does the mass of a transformer scale with frequency?I want to make a 120v 400 Hz power supply. I might boost my 48v up to200DC and use an isolated h-bridge out to the load, or we could putthe bridge down at 48v and boost with a biggish transformer.I'll have lots of air flow, so maybe I can push things some too.

And pretty cheap, as I can see. But the 1500 Vrms is a bit low.

I was refering to transport costs of matl. In the past, this also encouraged local mfr of LF magnetics.
