Question

2.120 pts] A schematic diagram of transformer is shown below. The closed path, l in the magnetic circuit in the Figure is traced by magnetic flux Ф. N,, N2, and 11, 12 are the numbers of turns and the currents in the primary and secondary circuits, respectively. The permeability, and cross-section of ferromagnetic core is, u and A İl(r) (a) [6 pts] Draw an equivalent magnetic circuit with two magnetomotive force, Vmmfi, and Vmmf2, magnetic closed flux, 4, and magnetic reluctance, Rand also write a loop equation for the magnetic circuit. of self-inductance, /, and v,(t) as a function of a load impedance, ZL addition, explain why "coefficient of coupling" must be existed in real transformer (b) [6 pts] If the transformer is an ideal transformer and is operated by i1(t) and i2(t), find the ratio (c) [8 pts] If the transformer is a real transformer, find vi(t), v2(t), mutual inductance, L12.
