(c) The dual-switch forward converter in Fig. Q4(c) is supplied from an input voltage Vin of 42V, and switches at 100kHz with a duty factor of 0.35. The transformer T1 carries 50 primary turns and 34 secondary turns. The core used in T1 has an effective area of 45mm2 and an effective length of 72mm. The relative permeability of its core material is =1790. [NB: The permeability of free space IS μ.-1.257×10-94/m.] V.D D, L1 TRI - 01 N1 N2...
