Flyback transformer EMC

Flyback transformer is a source of high frequency electromagnetic field.

Problem type:
Axisymmetric problem of Transient magnetics


flyback transformer

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

Calculate the magnetic field distribution around flyback transformer during operation cycle.

Model may be defined and solved as a Transient Magnetic Analysis problem.
