Pulse transformer simulation
TECircuit2: Pulse transformer
This is an example of the pulse transformer simulation, performed with QuickField software.
Plane problem of transient magnetics.
Magnetic permeability of the steel core μ = 500;
Conductivity of the steel core g = 0 S/m (steel 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.
Square voltage impulse applied to the pulse transformer. 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.
