Problem Type
Plane-parallel problem of transient magnetics.
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.
