Hello
I've recently come in to possession of four largeish ferrite E cores. The center leg of the core is 2.5cm x 2cm, or 5cm^2, the outer legs half that. Unfortunately the material is a mystery.
I'm pretty much a noob at SMPS design, but say if I wanted to use the cores for power transformers, what kind of power could they be ran at? Any ballpark figures?
An example of what I've had in mind was that I could wind some 2kV secondaries on them and run both center tapped for a nice +2kV,0,-2kV supply.

Virtually all power ferrite transformers are MnZn type of fairly high relative permeability. Yours is probably good for a few hundred watts. Several inverters have been built by members here, look at their designs and results first.
