Pulse transformer

QuickField simulation example

This is an example of the pulse transformer simulation, performed with QuickField software.

Problem Type
Plane-parallel problem of transient magnetics.

Geometry

Given
Magnetic permeability of the steel core μ = 500; electrical conductivity of the steel core is zero (steel core is laminated);
Conductivity of the windings (copper) g = 56 MS/m;
Number of turns of the primary winding w₁ = 20;
Number of turns of the secondary winding w₂ = 40;
Number of turns of the third winding w₃ = 20;
Pulse voltage U1 = 0.5 V, pulse duration t = 0.1 s.

Task
Calculate the currents in the windings.

Solution
Due to geometry model symmetry we leave the upper half of the transformer only. Therefore we should reduce the circuit elements' values by two.
