Square voltage impulse applied to the transformer.
Problem Type:
A plane problem of transient magnetics.
Geometry:
Given:
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 w_{1} = 20;
Number of turns of the secondary winding w_{2} = 40;
Number of turns of the third winding w_{3} = 20;
Pulse voltage U1 = 0.5 V;
Impulse time t = 0.1 s.
Problem:
Calculate the currents in the secondary winding.
Solution:
Due to model symmetry we leave the upper half of the transformer only. Therefore we should reduce the circuit elements' values by two.
