Flyback transformer EMC
magnetic field of flyback transformer, transient electromagnetic analysis
Flyback transformer is a source of high frequency electromagnetic field.
Problem Type
Axisymmetric problem of Transient magnetics
Geometry
Given
Ferrite permeability μ=1000,
Operation frequency f=1 kHz,
The transformer works in discontinuous mode, currents in windings are known:
Task
Calculate the magnetic field distribution around flyback transformer during operation cycle.
Solution
Model may be defined and solved as a Transient Magnetic Analysis problem.
Results
Magnetic field around the flyback transformer.
Magnetic flux density 1 cm away from the flyback transformer.
