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.

Pulse transformer Square voltage impulse applied to the pulse transformer. Calculation of the currents in the secondary and tertiary windings. U1 Filter Load Inductance Core Primary Secondary Tertiary

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.

Calculate the currents in the windings.

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