Flyback transformer EMC

Flyback transformer is a source of high frequency electromagnetic field.

Problem type:
Axisymmetric problem of Transient magnetics

Geometry:

flyback transformer

Given:
Ferrite permeability μ=1000,
Operation frequency f=1 kHz,
The transformer works in discontinuous mode, currents in windings are known.
