TECircuit2: Pulse transformer

Square voltage impulse applied to the transformer.

Problem Type:
A plane problem of transient magnetics.


Magnetic permeability of the steel core μ = 500;
Conductivity of the steel core g = 0 S/m (the core is laminated);
Magnetic permeability of the windings μ = 1;
Conductivity of the windings (copper) g = 56,000,000 S/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;
Impulse time t = 0.1 s.

Calculate the currents in the secondary winding.

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