The windings in the transformer shown in Fig. 5(a) are realized using copper foil layers arranged as shown in Fig. 5(b). The primary has 2 turns and carries high-frequency sinusoidal ac current 2i. The secondary has 4 turns and carries current i. The foil thickness is much greater than the penetration depth δ, i.e. ϕ >> 1. The copper loss due to current i through a copper layer of thickness δ is P .
